Breast cancer is a disease where cells in the breast begin to grow out of control. Breast cancer can spread outside of the breast and spread through blood vessels and lymph vessels.
Breast Cancer Symptoms
Breast lump – it is important that your physician examine it to determine whether it is cancerous
Thickening in an area of the breast
Change in the size or shape of a breast
Dimpling of the skin
Change in the shape of the nipple – if it turns in, has an irregular shape, or sinks into the breast
Blood stained discharge from the nipple
Rash on a nipple or surrounding area
Lump or swelling in your armpit
Breast Cancer Causes
Age – usually takes place following menopause
Family history – this doubles the risk when a primary relative has breast cancer
Breast cancer genes – These include BRCA1, BRCA2, TP53, and PTEN. It is possible to test for these faulty genes
Sex hormones and other hormones – women with high levels of estrogen and testosterone in their blood are more likely to develop breast cancer
Hormone replacement therapy – 3 out of 100 breast cancers in women in 2010 were linked to HRT use, based on a study from 2011
Contraceptive pills – there’s a small increase in risk while taking contraceptive pills, however this risk goes back to normal 10 years after stopping the intake of these pills
