A 60-year-old lady comes with blood stained discharge from the nipple with family history of breast cancer. Next best step for her will be:
Correct Answer: MRI
Description: Ans. d. MRI (Ref: Schwartz 9/447-450; Harrison 19/e p526; Sabiston 19/830-832; Bailey 26/799-801. 25/828-829)A 60-year-old lady comes with blood stained discharge from the nipple with family history of breast cancer. Next best step for her (high risk female) will be MRI for screening of breast cancer."There is current interest in the use of MRI to screen the breasts of high-risk women and of women with a newly diagnosed breast cancer In the first case, women who have a strong family history of breast canceror who carry known genetic mutations require screening at an early age, but mammographic evaluation is limited because of the increased breast density in younger women. In the second case, an MRI study of the contralateral breast in women with a known breast cancer has shown a contralateral breast cancer in 5.7% of these women. "--Schwartz 9/450"However, the ACS suggests (hat younger women who are BRCA1 or BRCA2 carriers or untested first-degree relatives of women with cancer; women with a history of radiation therapy to the chest between ages 10 and 30 years; women with a lifetime risk of breast cancer of at least 20%; and women with a history of Li-Fraumeni. Cowden, or Bannuyan- Riley-Ruvalcaba syndromes may benefit from MRI screening, where the higher sensitivity may outweigh the loss of specificity.
