Brief Answer: EXPLAINED BELOW Detailed Answer: Hello Thanks for writing to us with your health concern. Breast lumps are a common side effect of birth control. That is one reason I can think of. THe other is your age - 43 is near peri menopause. It is a time of hormonal fluctuations and changes, due to which again breast lumps are common. It is advisable to have a gynecological check up to ensure that the lump is benign, and does not mandate removal. In my opinion, it is more likely to be benign ( a small cyst or area of fibrosis or increased density ) as such changes are more common with birth control. The bump in the armpit could be an enlarged draining lymph node, that drains the breast. Given the lymph node too in conjunction with the lump, please go for clinical examination by a doctor and if necessary, imaging ( sonography and mammogram ). There is no cause for panic, as these changes are quite common, and more often than not, harmless. All the best Please feel free to discuss further.
