Survival Analysis of Female Breast <strong>Cancer</strong> by Stage<br />

Both diagnosis and treatment<br />

for female breast cancer have<br />

improved greatly since 1973.<br />

Due to mammography screening,<br />

more cases are diagnosed<br />

at an earlier stage. Currently,<br />

five-year relative survival for<br />

cases diagnosed at local stage is<br />

95% for women in the general<br />

population. For women with<br />

regional stage disease, survival<br />

has also improved. For women<br />

diagnosed with late stage<br />

disease, survival has remained<br />

relatively steady, at 10-20% for<br />

women in the general population.<br />

African American women<br />

tend to have a higher proportion<br />

of late stage diagnoses and<br />

five-year survival, regardless of<br />

stage, tends to be poorer than<br />

for Caucasian women.<br />

Gender and age are the greatest<br />

risk factors for developing<br />

breast cancer. Breast cancer<br />

can strike men and women<br />

both, but women are many<br />

times more likely to develop<br />

the disease than men. A family<br />

history of breast cancer has<br />

also been linked to increasing a<br />

woman’s likelihood of developing<br />

the disease. Gender, age,<br />

and family history are things<br />

that cannot be prevented,<br />

however women can increase<br />

their chances of surviving this<br />

disease by consulting with their<br />

physician, following recommended<br />

screening for their<br />

specific age and risk group, and<br />

by conducting monthly breast<br />

self-examinations starting at<br />

age 20. Women who are at an<br />

increased risk due to a family<br />

history should consult with<br />

their doctor about whether they<br />

should begin mammography<br />

screening at an earlier age than<br />

the recommended age of 40 and<br />

about the frequency of clinical<br />

breast examinations.<br />
