The term covers
a variety of malignant neoplasms and tumors, but simply put, "cancer"
describes a group of rapidly growing, abnormal
cells. This growth can occur in the breast tissue of either gender. Cancer
does not discriminate.
Everyone is
born with some breast
tissue. Hormones released at puberty cause girls to develop larger breast
ducts and other features, while male hormones prevent that growth. But the
man's tissue doesn't disappear. Women may be 100 times more likely to be
diagnosed with breast cancer, but the threat to men is no less real. Diagnosis
and treatment are similar across genders as well.
Scientists
have identified certain risk factors, such as family history, age and obesity,
but the causes of breast cancer are still mysterious. It is known that certain
changes in DNA can turn normal
cells cancerous. Researchers are actively investigating how certain genetic
mutations activate genes for cell division (thereby speeding up cell growth) or
suppress those genes that slow down cell division.
