I am a 25 years old male and I feel like I have hormonal imbalance after going through chemotherapy in 2012-2013 for osteosarcoma. I have put on a lot of weight after the treatment but gradually I have reduced my weight but I still have a lot of fat near my chest area and stomach and its looking odd. Moreover I suffer from fatigue, mood swings and nervous weakness. Can you suggest me the tests for hormonal imbalance or any other deficiency.
