HI,I have a set of twin grandaughters who are now nearly 6 yrs old. Both have always had bowed legs. My daughter has just informed me today that  1 of the twins has developed a noticeable lump on her knee. She is presently in the hospital and the doctors said it could be cancer. Can you please advise what the next step would be? My daughter lives 12hrs away and I am very worried for all of them. I am so worried. Carol.
Hi and welcome to Chat Doctor. Thanks for the query. Well, lump on knee isn't some specific sign of cancer and there are various possible diagnoses. Cancer is rare one, but should always be ruled out. I am sure that doctor will find right diagnosis so that treatment can be started as soon as possible. Wish you good health. Regards
