Good afternoon. My mom has recently been diagnosed with ovarian cancer and they are going to operate in the next 2-3 weeks. I am worried about how to care for her and what is involved. She is 78. Any advice would be amazing. Mom has a hysterectomy around 40 years ago but they left one ovary which is unfortunately the issue. It appears to be a very large tumour and the operation sounds rather tricky and lengthy with a lot of risk. Many thanks.
