Breast cancer occurs when cells in the
breast begin to grow out of control enabling them to invade nearby
tissues or spread throughout the body. Collections of these out of
control tissues are called tumors. However, not all breast tumors are
considered cancerous since certain types of large cells just cannot be
spread or threaten a person’s life and this kind of tumor is called
benign tumor. On the other hand, the tumors that can spread all
throughout the body or invade nearby tissues are considered cancerous
cells and are malignant. Cancer cells usually comes from either ducts
or glands in the breast that is why it may take months or even years
for a tumor to be notice in the breast. Breast tumors are screened with
the use of mammograms that are rather accurate in screening tumor or
cancer cells.
Women are much prone to develop breast
cancer that men. Only 1% to 2% of men have been known to have cases of
breast cancer. The early onset of menstruation in women at the age of
12 increases the risk for a breast cancer on the other hand an early
menopausal period may reduce the risk of breast cancer. The risk for
women to have breast cancer increases with age in fact a study shows
that women over 50 are more likely to develop breast cancer.
Nevertheless, the incidence of breast cancer among younger women is
also increasing in an alarming rate that is why more women of ages 20s
to 30s have subjected themselves to be diagnosed.
Breast cancer is not only acquired but
also can be inherited. For women who have genetic mutation such as
BRCA1 or BRCA2 has an 80% risk of developing breast cancer. Women who
have first-degree relative diagnosed to have breast cancer increase
their risk of also acquiring breast cancer. Moreover, women with
first-degree relative that are diagnosed to have breast cancer before
menopause increase the risk for them in acquiring breast cancer.
Some factors contribute to the occurrence
of breast cancer and these are as follows: smoking, alcohol and
radiation exposure. Women who are smoking will increase their chances
to have breast cancer. Aside from that, high intakes of alcohol have
been found to be a source of breast cancer. Radiation exposure is
another factor that contributes to breast cancer. Studies have shown
that women as well as children who have undergone high-dose radiation
therapy have a much higher chance of having breast cancer.
