Breast Cancer – Causes, Symptoms and Treatment

Breast cancer is a malignant (cancerous) disease that begins in the tissues of the breast. During  lifetime, one out of every eight women will be diagnosed with this cancer. Breast cancer is a type of cancer that affects both men and women. That is also one of the most well-known types of cancer tumors in humans. Breast cancer is the world’s fifth leading cause of cancer death (after lung most cancers, abdomen most cancers, liver most cancers, and colon most cancers).

Breast cancer kills more women in the United States than any other cancer except lung cancer. Breast most cancers, like other types of most cancers, are now thought to be the result of DNA damage. A number of known or hypothesized components contribute to how this mechanism works (corresponding to publicity to ionizing radiation, or viral mutagenesis). Some components cause an increased rate of mutation (exposure to estrogens) and decreased repair (the BRCA1, BRCA2, and p53) genes. Alcohol appears to increase the risk of developing this cancer.

Males are also at the risk

Males can get breast cancer, but it doesn’t happen very often. Breast cancer is expected to affect 178,000 women and 2,000 men in the United States, according to experts. Breast cancers are classified into several types. The first type of this is ductal carcinoma, which begins in the cells lining the ducts that carry milk to the nipple and accounts for more than 75% of all cases. The second type is lobular carcinoma, which begins in the milk-secreting glands of the breast but behaves similarly to ductal carcinoma. Other types of cancer can develop from the skin, fats, connective tissues, and other cells found in the breast.Some women are diagnosed with HER2-positive breast cancer. HER2, or human epidermal growth factor receptor-2, is a gene that regulates cell growth, division, and repair. Cell progress is sped up when there are too many copies of this gene in a cell.

Causes of Breast Cancer

The primary risk factor for breast cancer is simply being a lady. While men can get the disease, women are about 100 times more likely than men to get it. As a woman ages, her chances of developing this cancer increase. Almost 8 out of 10 breast cancers occur in women over the age of 50. Approximately 5% to 10% of cancers are linked to changes (mutations) in specific genes. The BRCA1 and BRCA2 genes are the most frequently altered. Breast cancer risk is higher in girls whose close blood relatives have the disease. The relatives could be from either the mother’s or father’s side of the family. Women who have had this cancer in one breast are more likely to develop the disease again in the opposite breast or in another part of the same breast. This is not the same as the primary cancers reappearing.

Many doctors now believe that the primary reason for this is that they have faster growing tumors. Asian, Hispanic, and American Indian women have a lower risk of developing breast cancer. Certain types of irregular biopsy outcomes may be linked to a slightly increased risk of cancer. Women who have had radiation therapy to the chest area (as a treatment for another cancer) earlier in life have a significantly increased risk of cancer.

Some pregnant women were given the drug DES (diethylstilbestrol) because it was thought to reduce their chances of miscarrying their child. Recent research has shown that these women (and their daughters who were exposed to DES while in the womb) have a slightly increased risk of developing breast cancer. The use of alcohol is clearly linked to a slightly increased risk of developing this cancer. Women who drink one drink per day are at a very low risk. Those who consume two to five drinks per day have approximately 112 times the risk of women who do not consume alcohol.

You have to limit alcohol consumption

The American Cancer Society recommends that you limit the amount of alcohol you consume. Obesity is linked to an increased risk of breast cancer, particularly in women after menopause and if the weight gain occurred during maturation. Also, the chance appears to be greater if the extra fat is located around the waist. Breast-feeding and pregnancy: Some research has shown that breast-feeding only slightly reduces the risk of breast , particularly if the breast-feeding period lasts 112 to 2 years. This could be because both breast-feeding and pregnancy reduce a woman’s total number of menstrual durations. Women who began having periods early (before the age of 12) or who went through the change of life (menopause) after the age of 55 have a slightly elevated risk of this cancer.
