My wife was diagnosed with breast cancer

I think you should discuss your concerns. It is so important for both of you to have a positive attitude. My husband has the best outlook on life even though he is going through his second round of cancer. He was first diagnosed in 2002. I will not even go through all he had to go through with his primary care physician who kept insisting he had acid reflux, then ulcers. He had colon cancer, had surgery, and went through a year of chemo. 4 and 1/2 years later it reappeared in 3 lymph nodes. He went through 6 more months of aggressive chemo which cleared 2 of the lymph nodes, and we are still working on the third. Think positive thoughts and be hopeful.
