Hi, Thanks for writing in. It is important to read complete reports to know exactly which type of bone caner is present in your mother. There are some which are aggressive and few that are slowly progressive. By definition, a cancer is an uncontrolled proliferation of abnormal cells. Some cancers respond well to surgery in the early stages. Radiation therapy and chemotherapy also help. After getting MRI, CT scan and bone scan, it is important to get the FNAC and biopsy reports before you start treatment. This is the basis of a confirmatory diagnosis of the bone cancer and its cell type. CT and MRI scan will tell the extent and involvement of adjacent structures. Bone scan will tell if there is tumor spread to other parts of the body and if the cancer is involving more than one bone. Please discuss the biopsy report and MRI findings and then start treatment as suggested by her doctor. Giving the patient adequate nutrition is important to better treatment response. Please do not worry.
