Although there are many non-genetic causes of breast cancer, mutations in BRCA-1, BRCA-2 and PTEN genes have been identified in some family trees.
Is Breast Cancer Genetic?
Approximately 5–10% of breast cancers are hereditary. Women carrying BRCA1 or BRCA2 gene mutations may have a lifetime breast cancer risk of 50–85%. Genetic counselling is recommended for individuals with a family history.
Does Breast Cancer Only Occur in Women?
No. Breast cancer can occur in men too, but it accounts for only about 1% of all breast cancer cases.
Do Breast Implants Increase Cancer Risk?
Scientific research shows that standard silicone or saline breast implants do not increase the risk of breast cancer.
Is Breast Cancer Treatable?
For breast cancer diagnosed at an early stage, the complete recovery rate is very high. The 5-year survival rate for Stage I breast cancer exceeds 95%.
Is Chemotherapy Unavoidable?
Every breast cancer case is different. Depending on the tumour's biological characteristics, stage and hormonal status, chemotherapy, radiotherapy, hormone therapy or targeted therapy may be chosen.
