Cancer is a term that has a broad meaning. However, Breast Cancer starts from the cells found inside a breast. They can then spread towards other areas of a body if not treated on time. The occurrence starts when malignant tumors develop inside the breast. These cells start spreading away slowly and begin to enter the blood vessels and then branch out to different tissues of the body. As they travel to different parts of the body they start damaging different areas and organs.
Breast cancer symptoms in men are most likely similar to those in women. Most male breast cancers are diagnosed when a man discovers a lump on his chest. But they tend to delay going to the doctor until they have much more severe symptoms like bleeding from the nipple. At that point it is possible that the cancer may have already spread throughout the body.
Getting older- a women’s age contributes as a factor to developing breast cancer. As the age increases the risk of developing breast cancer increases.
Genetics- A woman who has close relatives who have/had breast or ovarian cancer are more likely to develop breast cancer.
A history of breast cancer- Women who have had breast cancer, even non-invasive cancer, are more likely to develop the disease again, compared to women who have no history of the disease.
Having had certain types of breast lumps- Women who have had some types of benign (non-cancerous) breast lumps are more likely to develop cancer later on.
Dense breast tissue- Women with more dense breast tissue have a greater chance of developing breast cancer.
Estrogen exposure- Women who started having periods earlier or entered menopause later than usual have a higher risk of developing breast cancer. This is because their bodies have been exposed to estrogen for longer.
Obesity- Post-menopausal obese and overweight women may have a higher risk of developing breast cancer.
Height- Taller-than-average women have a slightly greater likelihood of developing breast cancer than shorter-than-average women.
Alcohol consumption- The more alcohol a woman regularly drinks, the higher her risk of developing breast cancer is.
Radiation exposure- Undergoing X-rays and CT scans may raise a woman's risk of developing breast cancer slightly.
HRT (hormone replacement therapy)- Both forms, combined and estrogen-only HRT therapies may increase a woman's risk of developing breast cancer slightly.
