Keep an open mind to the treatment options available to you. I found that for me my best weapon I had against cancer was to trust my doctor’s advice and listening to their expertise. If a treatment plan wasn’t comfortable for me, my doctor truly listened and changed to another plan. We no longer have a ‘one treatment plan only’ for breast cancer offered to us. There are options available. It won’t cause any harm to having an open mind and listening. At 72 you likely have a good many years still available to enjoy loved ones. Much love to you! And Good Luck!
