Advanced age an being female increases the chances of getting breast cancer.

2. History of breast cancer in the family and inherited genes 

Having a mother,sister or a daughter with breast cancer increases the risk of getting breast cancer.

Having more close relatives  with breast cancer  or one who got cancer under the age of 50 increases the risk as well.

Sometimes one can inherit genes that are faulty  and that increases the risk of getting breast cancer.Two types of the faulty gene include BRCA1 and BRACA2 genes.However having these genes does not mean one will always get the cancer.

3. Not having children or having them later in life
