Breast Cancer (Breast Cancer) What is breast cancer? One in nine women develop breast cancer at some point in his life. This is a major cause of death for women aged 34 to 54.
Although there are some change due to better treatment and early detection, England is a country with the highest mortality rate for breast cancer in the world. But research is beginning to reap dividends in a new way to understand how breast cancer cells work.Breast cancer is a malignant disease (cancer) cells form in breast tissue. DNA damage to cells results in uncontrolled cell division in growth, and, finally, sufficient cells accumulate to form lumps. Tues invade the surrounding normal breast tissue and can be broken into lumps of primary spread in the lymph channels or bloodstream to other organs where secondary lumps (metastases) can be formed.
Breast is divided into the ducts and lobules. The most common form of breast cancer emerged from the channel and is known as invasive ductal carcinoma. Cancer arising from the lobules (lobular invasive carcinoma).
Like most cancers, the key to successful treatment is early diagnosis of cancer before it has had a chance to spread to other organs
Causes of Breast Cancer
One good reason why most women affected by breast cancer is still unknown, but considered as a combination of genetic, environmental and lifestyle. Scientists have identified two genes that are more likely to include damage to someone with breast cancer. This gene also cause for some other cancers. However, even these two mutated genes thought to be responsible only for about five to 10 percent of cases of breast cancer.
Hormones seem to have an important role in breast cancer.Studies have shown a relationship between levels of estrogen (female sex hormone) and breast cancer risk. The exact cause of breast cancer has not been clearly identified, but there are several contributing factors including.
Breast cancer genetics
- The older - 80 percent of cases of breast cancer in postmenopausal women - it is relatively uncommon in young women
- has a significant family history of breast cancer, which may be associated with gene mutations
- heritage does not have children or women who had their first child in their old age
- Start early menarche or late menopause
- Process some types of hormone replacement therapy (HRT) for menopause in the long term
- Overweight excessive
- alcohol drinking and
Less than one of 20 cases of breast cancer are declining, so if a relative has breast cancer is most likely a coincidence.However, you should be more careful if you have:
- relative who was diagnosed under age 40 will develop cancer
- close relative with cancer in both breasts male relative with breast cancer
- Two close relatives on the same side of the family diagnosed with breast cancer under 60 or with ovarian cancer
