My mother, of 53 years old, have been taking a single dose of Newbona Fem tablet everyday, for around 1 year 2 months, since she is a patient of Severe Osteoarthritis in lower backbone and knee. Today I have seen in net that Newbona Fem tablet can develop cancer in a person. I have told my mother to stop that medicine. I just want to know that does my mother has a chance of developing cancer? Please kindly reply.
