question: Hello, my mother (53 yo, ex-smoker) was diagnosed with lung cancer last summer. She had surgery(left lung lobectomy). The biopsy revealed lung adenocarcinoma , without lymph node involvement and only localized damage. All post surgery ct did not reveal any problems to other organs or the brain. Yesterday she had a brain CT which revealed a 18mm tumor in the left bregmatic area of the brain and was advised to do radiaton therapy which we booked for thursday. Is there any chance for long term survival?
