Welcome to HCM!
I would like to tell you that cancer is such a common disease that it is no surprise that many families have at least a few members who have had cancer. Sometimes, certain types of cancer seem to run in some families,but only a small portion of all cancers are inherited.
You had thyroid
growth which was not malignant so nothing to worry.Now for acute and chronic RA,Its true that there is no cure for RA, but treatments can improve symptoms and slow the progress of the disease. Disease-modifying treatment has the best results when it is started early and aggressively.Regular exercise is recommended as both safe and useful to maintain muscles strength and overall physical function.
I sincerely hope this will help you!TAKE CARE!
