Answer:
Environmental or non-genetic factors are responsible for 90-95% of breast cancer diagnoses.
Explanation:
An abnormal growth that has grown from breast cells is referred to as "breast cancer." The granular, and/or/ or the ducts, the passageways that carry milk from the glandular tissue to the nipple, are often where breast cancer starts. Cancer cells can slowly infiltrate neighbouring healthy breast tissue and go to the nearby lymph nodes, which are tiny structures responsible for filtering out unwanted substances from the body. Cancer cells possess a route into other bodily organs if they enter the lymph nodes. The stage of breast cancer describes how far the disease has progressed from the initial tumour.
