Hello. I'm sorry to hear about your diagnosis and the worries you are experiencing. Many of us have been through this and have come out the other end smiling. It sounds like you're in very good hands and that you will soon hear what treatment is in store. If surgery is planned you will certainly need a bit of help for a few days when you get home. In my case I was diagnosed last October, had an operation in November and was discharged from hospital after 4 days and cared for by my wife, who deserves a medal. After a few days I was able to generally look after myself and prepare meals etc. and get exercise. Then followed 3 months of chemo which was a bit tough at times but didn't stop me getting around and doing near-normal activities.
Best of luck - I'm sure you'll get through it.
