What is the most effective method to identify early breast cancer lumps?
A . Mammograms every 3 years
B . Yearly checkups performed by physician
C . Ultrasounds every 3 years
D . Monthly breast self-examination
Answer: D
Explanation:
(A) Mammograms are less effective than breast self-examination for the diagnosis of abnormalities in younger women, who have denser breast tissue. They are more effective for women older than 40.
(B) Up to 15% of early-stage breast cancers are detected by physical examination; however, 95% are detected by women doing breast self-examination.
(C) Ultrasound is used primarily to determine the location of cysts and to distinguish cysts from solid masses.
(D) Monthly breast self-examination has been shown to be the most effective method for early detection of breast cancer. Approximately 95% of lumps are detected by women themselves.
