What is Breast Cancer?
Breast Cancer starts in the breast with a malignant tumour. This malignant tumour is a mass of cells which grows out of control. The cancerous cells can move to other tissue or other parts of the body. Cancer can develop in any of the three types of breast tissue as lobules, ducts and connective tissue.
Most cancer begins in lobules (the milk-producing gland) or in the ducts (along which milk travels to the nipple). Non-invasive breast cancer tumours can develop in fibrous and fatty connective tissue which surrounds lobules and ducts; breast cancer which grows into normal tissue is called invasive breast cancer. Several types of breast cancer exist; treatment of breast cancer depends on the type of breast cancer, its stage and its growth area.
Breast Cancer is Common and it is good that cases are going down.
It is good news that Breast Cancer cases are decreasing from the year of 2000, and it is declining every year. Every year about 30 per cent Breast cancer cases are diagnosing in women and 15 per cent of all new cancer diagnoses each year. According to the data, one in eight women has been diagnosed with invasive breast cancer once in their lives.
The disease found more common in the middle age group of women as between the ages of 55 to 64. Among other women, black women have the highest risk of breast cancer; Black women are more likely to die from breast cancer than women of other races. The death rate is decreasing since 1989 and the majority of women survived this cancer.
Breast Cancer: CAUSES
There are exact causes of breast cancer are still unknown; as a general fact, we know that disease occurs when some breast cells begin growing abnormally. These cells divide more rapidly than healthy cells and forming a lump or mass.
These cancer cells may spread throughout the breast and into lymph nodes or to other parts of your body.
There are several lifestyles, environmental and hormonal factors which may increase the risk of developing breast cancer.
There are some traits which increase the risk of breast cancer
- Being a woman
- Older age
- Personal history of carcinoma in one breast
- The family history of breast cancer
- Inherited genetic mutations as BRCA1 and BRCA2
- Radiation exposure
- Giving birth the first time after 35.
- Never being pregnant
- Taking hormone therapy which combines estrogen and progesterone
Inherited Breast Cancer
Most of the breast cancer cases are not inherited, infect only 5 to 10 per cent cases comes in genetic mutations. The most gene linked to breast cancer in BRCA1 and BRCA2. In normal cells, the BRCA1 and BRCA2 genes help to prevent cancer by making proteins, which keep the cells from growing abnormally but if these genes are mutated the cancer prevention response will not work properly.
More risk with the BRCA1 and BRCA2
For some of the women with the BRCA1 mutation, the lifetime risk of breast cancer is 80 per cent and with the BRCA2 mutation, the lifetime risk of breast cancer is 45 per cent. Cancer in both breasts is also common than in cases not connected to these BRCA mutations. These mutations occur more often in younger women.
Men also carry these mutations and if they do; they are at increased risk of breast and other as prostate cancer.
If you have a genealogy history of breast cancer diseases or other then you should definitely prepared for Genetic Testing; through a blood or saliva test, specific inherited mutations in BRCA or other genes are possible to identify. You should talk to the doctor about genetic testing suitability for results. Your doctor may recommend a genetic counselor who will discuss your testing options in detail.
Finding a best treatment team
After receiving a diagnosis, you need to decide for a healthcare provider who will handle your treatment; you need to care for some factors to choose your oncologist and a good treatment team.
Even after you have a consult treatment team, it’s a good idea to look for another oncologist and get a second opinion for diagnosis & treatment options. It is acceptable to change doctors during your treatment if needed.
