<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, My mom had grade II breast cancer and every thing is completed including chemo and radiotherapy. Now she is having vitamin D deficiency. Doctor is recommending vit D injections. Is it okay to take those injections because i heard injections are painful and have side effects apart from its cost.Thank you  <response>: Hi, dairy have gone through your question. I can understand your concern. She had breast cancer. She completed the treatment. But if she has vitamin D deficiency then she should take vitamin D supplements. Because low level can lead to weakened bone. So go for vitamin D level once and then take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
