My mother was in her early 60's when 1st diagnosed with breast cancer. It was very hard as this was back in the early 80's & we did not have the phone services that we do today. I was 300 miles away and a full time teacher & in the midst of having a house built. I regret not having spent more time with her before she lost her battle.
If you don't have Skype on your computer, I suggest you do it. It's totally free & the best thing you can do for your mom in let her talk & know that she is not alone in her battle.
