Yes, cancer can be genetic. Breast cancer is an example. I don't know if all cancers are genetic but I suspect that they are not. I often hear of cancer in a family in which no one else has had cancer.
I had a carcinoid tumor in my lung. Carcinoid is a form of cancer that is slow growing. The doctor said it had probably been there for 20 years or more. They found it when they took an x-ray to confirm or rule out pneumonia. It was the size of a quarter. They determined what kind of a tumor it was by going inside my lung thru my mouth while I was under twilight anesthesia. If the tumor had not be cancer they would not have operated.
I did have surgery and one lobe removed. I've been cancer free for 6-7 years now. And I don't miss that one lobe.
I know how scary it is while you wait to get more information. I think that the fact that your great grandmother had a similar tumor in the same place and lived to 70 is a very good sign. Do you know why she died. I was told that I could probably, but not for sure, live to die from some other cause if I decided to not remove the tumor. I just felt like I didn't want to take the chance. I'd had several abdominal surgeries and felt comfortable with a surgery. It was the easiest surgery I'd had. They have so much better drugs now then when I was younger and having surgery.
Since your tumor does not involve the brain or bone, I would think that even if you do have it out the surgery will go well.
I trusted my gp and went to the specialist that he recommended. I saw a pulmonologist first to find out if the tumor was cancerous or not and then he referred me to a surgeon. I was able to read about the clinic that these two doctors practiced in and felt comfortable with both of them from the start. If a cancer diagnosis and surgery can be considered good this was a good, tho scary, experience.
I've read and I believe based on my own experience that the most important part of surgery is trusting your surgeon and the hospital in which the surgery takes place. I don't know the hospitals you mention but if they have a good reputation go there. Listen to the doctors and if you feel a sense of calm and trust then use those doctors. If not find another one.
One reason I decided to have the surgery is that I didn't want to have that tumor on the back of my mind forever. It also helped that the doctor said that he would have it out if it were in his lung.
Whether or not your tumor is the result of your genes doesn't change much. You have it. The question I would ask is is this tumor the sort that migrates to other parts of the body or has migrated from another part of the body. Now that I write that. the main reason I had surgery was a carcinoid can migrate. I had full trunk CT scans for 5 years after the surgery.
Hang in there. Sounds like you'll be back to normal before you know it. If you're feeling really anxious, ask for Ativan or one of those medications to take short term. I didn't need an antianxiety med for the cancer experience but when I needed an MRI of my head because I was dizzy I did need the Ativan. Also, during the MRI procedure they gave me Valium introvenously. If you haven't had a MRI before and you are feeling very anxious you might ask them, ahead of time, to consider the possibility of using Valium. Also you can ask about using a machine with a wider opening and having music piped in. That helped me a whole lot. An open machine is not so good because the pictures are not as sharp. I suggest that finding out more about the actual procedure with the MRI might be helpful. You can find info on the Internet.
