I have recently finished treated for a grade 3, left breast cancer with lymphatic involvement, sectional removal, lymphatic clearance, chemo 6 1/2 months, radiotherapy 6 weeks of 5 times a week. I was very fit at the commencement of apparently fairly aggressive chemotherapy, as I was told there was a chance of metastases. Diagnosed feb 27 2013, 56 years old. I am a positive person and have been involved in the medical profession. I have noticed a lump just above my left groin, no pain and intermittent. I attend the gym twice a week and do sport twice a week with no pain in this area. I assume it is nothing to be concerned about in regard to cancer !
