A previous post (February 9 2011) looked at issues involving both risks and benefits of screening for breast cancer. The link below summarizes the US Preventative Services Task Force’s recommendations on screening. For ages 50-79 a biennial mammo is recommended. Many other societies still recommend an annual. In the 40-49 year old age group, the second link below clarifies who may benefit from mammography. In short, in the 40-49 year old age group, if one has a first degree relative with breast cancer (mom, sister) or has “dense breasts” on mammo (meaning that at least one mammo is necessary in this age group), then regular mammo’s starting at age 40 are probably a good idea.
