Why People Difficult to Stop Smoking

http://endurance-mom.blogspot.com/A new study published in the journal Biological Psychiatry found that the habit of smoking can reduce the thickness of the human brain.

Researchers compared the thickness of the cortex on volunteers, both smokers and who had never smoked, who have no medical or psychiatric illness. The cortex is the area of the brain that is responsible for many important functions, including language, information processing, and memory.

The result is stunning. People who smoke thinned cortex in the left middle orbitofrontal. People who smoke more frequently, according to the study, depletion of cortical networks will be increasingly obvious.

These findings show, with thinning of the cortex, then the risk of becoming a drug addict rose, even she will increasingly become heavy smokers.

Because of the thinning, it will be associated with impulse control, reward processing and decision making. This condition may explain how someone can become addicted to nicotine.

Six Causes of Menstrual Cycles Not Regular

http://endurance-mom.blogspot.com/
Every woman has a menstrual aeon is different. Some acquaintance it 10-11 times per year. There are 13 times per year. In fact, there are added or less. This happens because every woman has a character of anniversary hormone that affects fertility.

Normal menstrual aeon describes the action of basic a acceptable egg. Ideally, women acquaintance menstrual cycles amid 21 to 35 days. The aeon is affected from the aboriginal day of menstruation until the endure day afore menstruation in the next month.

However, women about ache from hormonal imbalances that advance to menstrual irregularities in the aboriginal few years to get menstruation and menopause.

There are several factors that can agitate the menstrual aeon of women, as quoted by the Times of India pages.

1. Weight unstable
Increase or abatement in physique weight so acutely affect the absolute physique system. This is of advance aswell affect hormones that automatically plays an important role in acclimation the menstrual cycle.

2. Bistro disorders
The action of the physique that banned aliment because he capital to get acclimated to consistently feel athirst (anorexia), the addiction of bistro affluence of aliment and again expelled by airsickness (bulimia), and the attraction has a able diet and advantageous diet (orthorexic nervosa) can agitate a woman's account cycle.

3. Abundant activity
Some women who abide abundant exercise or action that is actual backbreaking aswell at accident of aberrant cycles.

4. Stress
Lifestyle abounding of stress, illness, ancestors planning, treatment, and hormone problems can could cause changes in hormone production. While the hormone is bare by the physique to
support the accident of menstruation.

5. Nurse
Women who breastfeed for added than a year afterwards giving bearing will not get a approved cycle. However, this does not beggarly you can not get pregnant. If you wish to adjourn pregnancy, do not belittle the aberrant cycles during lactation. Continue application contraception to abstain pregnancy.

6. Health problems 
Another agency is the abortion of the absolution of an egg by the uterus acquired by surgery, chemotherapy or radiation analysis application on the achievement of women. The experts aswell say that the aeon irregularities aswell action because of diseases such as tuberculosis, liver, and diabetes.
Sometimes even no credible acumen which resulted in women experiencing aberrant cycles. Try to calm down. There may be a hormone alterity causing your O aeon is uncertain. To be sure, do a abundance analysis or go to the doctor for it checked.

Toxins in Cigarettes

http://endurance-mom.blogspot.com/
Maybe you anticipate abandoned smoker a cigarette abandoned will not could could cause bloom problems. Anticipate again. Therefore, American scientists activate a cigarette is abundant to block arteries and activate affection attacks.

Tobacco smoke contains hundreds of baneful chemicals can anon could could cause accident to organs. In a contempo abstraction surgeon activate no safe akin of acknowledgment a being apparent to cigarette smoke, both for alive smokers and acquiescent smokers.

This is because the cigarette smoke seeping anon into the bloodstream, chemically alteration the agency so that the array and arterial pressure. As a result, the avenue anchorage and closed. The address aswell activate that even acknowledgment to cigarette smoke in a abbreviate time can activate a affection attack.

However, for those who wish to abdicate smoking, never too late. Start now! Because, in the address aswell declared what happens in the physique if a being stops smoking

- 20 minutes: Claret burden and beating amount acknowledgment to normal

- 8 hours: Nicotine and carbon monoxide levels in the claret is bargain bisected and oxygen aback to normal.

- 24 hours: Carbon monoxide is absent from the body. The lungs activate to annihilate fungus and added smoker kototran result.

- 48 hours: The physique absolve nicotine from the body. The adeptness to feel the faculty of that appears to smell and aftertaste increases

- 72 hours: Breathing becomes easier. Bronchial tubes activate to relax and access activity levels.
- 2-12 weeks: apportionment improves.

- 3-9 months: Coughing, and respiratory problems access with advance in lung action by 10 percent

- 5 years: Accident of affection advance drops to about bisected compared to the smokers.

- 10 years: Accident of lung blight is bisected of the smokers. The accident became agnate to the non-smokers.

CANCER TREATMENT: Surgery

Oncologists select from a number of options when treating cancer, depending on the type and stage of the tumor involved. The major treatments currently available are surgery, radiation therapy, chemotherapy, hormone therapy, and immunotherapy. Often, targeting cancerous tumors requires the artful combination of more than one type of cancer therapy.

Surgery is the most effective and fastest treatment for tumors that are caught early and have not metastasized. It is the only option ensuring that the entire visible tumor is eliminated. However, there is no guarantee that all microscopic extensions of a tumor have been removed. For this reason, surgeons may also remove a large portion of healthy tissue that surrounds the tumor. This may not be possible if the tumor lies near or within a vital tissue, such as a major nerve or organ.

Often, cancer surgery requires general anesthesia, in which the patient loses consciousness, and a hospital stay of several days. For example, women with breast cancer may have a lumpectomy or mastectomy, surgical removal of part (or all) of the breast. Depending on the stage of the tumor, doctors may also remove the nearby lymph nodes and muscle tissue. As with any major surgery, mastectomies and other major surgical cancer treatments involve some risk, and doctors must consider the overall health of the patient, as well as the stage of the tumor.

Some cancers can be treated surgically with less-invasive techniques, such as laser surgery. Laser surgery uses a powerful beam of high-energy light to vaporize certain tumors of the cervix, larynx, and skin. Physicians perform laser surgery with an endoscope inserted through a small incision in the skin. Laser surgery and other less-invasive surgical procedures may require only local anesthesia, in which a patient loses feeling in one particular area of the body but never loses consciousness.

Sometimes oncologists recommend surgery to improve a patient’s quality of life, even if it is not likely to rid the body of cancer. Surgery of this type aims to correct a problem that is causing discomfort or disability. For example, some cancers may spread to the spine, pressing on the spinal cord or nearby nerves. This pressure may cause severe pain, and in some instances, paralysis. Surgical removal of all or part of the tumor near the spine may alleviate these symptoms.

DIAGNOSA CANCER BY STAGING


In previous writings I wrote an article Diagnosis of Cancer by Detection of Cancer, now I'll write a continuation of the article. When a tumor is detected, the physician takes a biopsy by removing a sample of the tissue. The biopsy sample is inspected under a microscope to determine if the tumor is benign or malignant. Cancerous cells usually appear abnormal in shape and no longer orient themselves in orderly configurations. If the tumor is cancerous, the physician assigns it a stage, indicating how far cancer has spread. The stage is a key factor in determining both the cancer’s treatment and prognosis.

Oncologists, physicians who specialize in the diagnosis and treatment of cancer, use several different staging systems. In one system, tumors are grouped into four stages denoted by Roman numerals I through IV. Stage I cancers are small localized cancers that are usually curable. Stage II and III tumors are usually locally advanced and may or may not have invaded nearby lymph nodes, and stage IV tumors have usually metastasized—that is, spread to distant tissues in the body.

The most widely used staging system is the Tumor, Lymph Node, and Metastasis system, commonly abbreviated TNM. This system uses numbers between zero and three to assess the size of the tumor (T), the extent that it has spread to nearby lymph nodes (N), and the extent that it has spread throughout the body (M). A cancer’s stage depends on a combination of these numbers. For example, a T-1, N-0, and M-0 tumor is a stage 1 tumor. This tumor is 2 cm (1 in) or less (T-1) and has not spread to nearby lymph nodes (accounting for N-0) or metastasized (M-0). The five-year survival rate for a patient with this stage tumor is accordingly excellent. A T-3, N-1, and M-0 tumor is a stage 3 tumor.

This tumor is greater than 5 cm (2 in) and has spread to nearby lymph nodes, but there is no evidence that the cancer has spread to distant tissues. The five-year survival rate for a patient with this tumor is not as high as the T-1, N-0, M-0 patient. Stage 4 tumors are distinguished by an M-1 number. This means they have progressed to the point where metastasis is widespread, and the prognosis is usually quite poor.

DIAGNOSIS OF CANCER BY DETECTION OF CANCER



Diagnosis of cancer often begins when a person notices an unusual health symptom and consults a doctor. Early warning signs of cancer include changes in bowel or bladder habits, a sore that does not heal, unusual bleeding or discharge, thickening or a lump in the breast or any other part of the body, indigestion or difficulty swallowing, change in appearance of a wart or mole, or a nagging cough or hoarseness.

People with early warning signs should consult their family doctor, who will evaluate symptoms and may refer the patient to a physician who specializes in cancer. A physician will first take the patient’s medical history to learn about current symptoms, past history of disease, and family members diagnosed with cancer. The procedures used in a physical exam depend on the patient’s clinical symptoms and may include a digital rectal examination, in which the physician uses a gloved finger to gently check the smoothness of the rectal lining. The physician may perform a breast exam on female patients, in which the breasts are gently probed to feel for lumps or unusual masses.

During the examination the physician may use a thin, lighted tube called an endoscope to look for tumors in internal body cavities. The endoscopy procedure used depends on the organ or body cavity examined. In gastric endoscopy, the doctor feeds a specialized endoscope down the throat to examine the lining of the esophagus, stomach, and first part of the small intestine. Fiberoptic sigmoidoscopy, in which a flexible instrument is inserted into the lower intestinal tract through the anus, enables a physician to visually examine the interior of the colon and rectum. Colonoscopy uses a much longer flexible instrument to view the entire length of the large intestine.

A number of laboratory tests help narrow the possible diagnoses. In a Pap smear, cells are removed from the cervical epithelium with a small plastic brush. These cells are examined under a microscope for cell changes that are a sign that cancer may be developing as well as signs of malignancy. If a patient’s clinical signs suggest colorectal cancer, the doctor may search for blood in the stool using a fecal occult blood test. A small sample of the patient’s stool is smeared on a card coated with a chemical called guaiac, which reacts with blood. The card is analyzed in a laboratory for occult (hidden) blood. Certain blood tests determine if levels of red and white blood cells are low, a possible indication of leukemia. Others test for the presence of tumor markers, chemicals that are present in higher levels when certain cancers are present. For example, a prostate-specific antigen (PSA) test measures levels of prostate-specific antigen in the blood. Prostate cancer cells overproduce this protein, causing an elevation of PSA levels in blood.

Medical imaging techniques help doctors locate and evaluate a tumor. These include computed tomography (CT) and magnetic resonance imaging (MRI) scans. CT and MRI scans use computers to form a three-dimensional image of the tumor and surrounding tissues. X-ray images of the breast called mammograms help physicians detect and evaluate breast cancer. Ultrasound scanning bounces high-frequency sound waves off a tumor and surrounding tissue to create an image of the tumor. The multimodality display technique combines the images from several imaging tools into one picture, providing a final three-dimensional image with much greater detail. Computer-aided diagnosis uses complex computer programming technology called artificial intelligence to scan mammograms and X rays to help look for signs of cancer and offer an automated second opinion.

CAUSES OF CANCER

Cancer can develop in the human body, where this discussion has been detailed in previous posts. In this article will discuss about the things that cause cancer.

Scientists do not fully understand the causes of cancer, but studies show that some people are more likely to develop the disease than others. Scientists called epidemiologists study particular populations to identify why cancer rates vary. One method they use is to compare cancer patients with healthy people in terms of behavior such as diet, exercise, and smoking and traits such as gender, age, and race. Population studies provide useful information about risk factors that increase the likelihood of developing cancer.

1. Carcinogens

One of the greatest risk factors for cancer is prolonged or repeated exposure to carcinogens—chemical, biological, or physical agents that cause the cellular damage that leads to cancer. The details of how carcinogens cause cancer remain unclear. One theory is that exposure to carcinogens, when combined with the effects of aging, causes an increase in chemicals in the body called free radicals. An excessive number of free radicals causes damage by taking negatively charged particles called electrons from key cellular components of the body, such as DNA. This may make genes more vulnerable to the mutating effects of carcinogens.

2. Hereditary Factors

Evidence suggests that heredity plays a role in developing cancer. Some gene mutations associated with cancer are inherited. For example, inheriting mutated tumor suppressor genes BRCA1 or BRCA2 greatly increases a woman’s chances of developing breast cancer. About 50 to 60 percent of women with inherited BRCA1 or BRCA2 mutations will develop breast cancer by the age of 70. Inherited mutations in the genes MSH2, MLH1, PMS1, and PMS2, all of which repair DNA, are especially prevalent in a rare form of hereditary colon cancer.

Scientists suspect that many other hereditary factors contribute to cancer. In addition to inherited mutations, other genetic variations, particularly those influencing how the body responds to carcinogens, may create a greater susceptibility to cancer. The identities of the majority of these genetic variations are not yet known.

3. Steroid Hormones

Medical research suggests that cancers of the reproductive organs may be affected by naturally occurring steroid hormones produced by the endocrine system. These hormones stimulate reproductive organ cells to divide and grow. In women, relatively high or long exposure to the female sex hormone estrogen seems to increase the risk of breast and uterine cancers.

Thus, early age at first menstruation, late age at menopause, having a first child after age 30, and never having children, all of which affect the duration of estrogen exposure in the body, increase the risk for these cancers. Studies also indicate that hormone replacement therapy (HRT), in which women take estrogen to offset the unpleasant effects of menopause, increases the risk of breast cancer. Male sex hormones, particularly testosterone, appear to play a role in cancers of the male reproductive organs, but this role is not yet well understood.

4. Population Demographics

Population studies show that a person’s age, race, and gender affect the probability that he or she will develop cancer. Most cancers occur in adults middle-aged or older. The risk of cancer increases as individuals age because genetic mutations accumulate slowly over many years, and the older a person is, the more likely that he or she will have accumulated the collection of mutations necessary to turn an otherwise healthy cell into a cancerous cell.

More than three-fourths of all cancers in North America are diagnosed in people over age 55. Statistics show that men are more likely to develop cancer than women. In the United States, nearly half of all men will develop cancer at some point in their lifetimes, whereas slightly more than one-third of women will.

Stomach cancer is nearly twice as common in men as in women, as are certain types of kidney cancer. However, the reasons for the discrepancy between the sexes are unknown. Some cancers are more prevalent in particular races than others. In the United States, for example, bladder cancer is twice as common in white people as in black people. White women are slightly more likely to develop breast cancer than are black women, but black women are more likely to die of the disease.

Asian, Hispanic, and Native American women have the lowest breast cancer risk. On the whole, African Americans, especially men, are more likely to develop cancer—and more likely to die from it—than members of any other group in the United States. Reasons for the discrepancies between races are still not entirely clear, but many epidemiologists trace them to differences in diet and exercise, unequal access to medical care, and exposure to carcinogens.
