My sister was diagnosed with IMA lung cancer this July. It was found during the physical exam. She is 55 years old, otherwise very healthy and active, and has never smoked. Since the tumor was very big, 4.4 cm, the doctor scheduled surgery and removed the lower lobe of her right lung in mid-July and said it is stage 2A. The PET scan and the examination of the tumor tissue did not find any spread. But according to her doctor, since the tumor was so big, and the cancer sub type of "mucinous" is of especially high risk of possible recurrence, the 5 year survival rate is very low, I am very scared. I have been trying to find more information about this sub type of lung cancer IMA. But it does not seem to have many posts out there talking about this type. I wonder if it because it is indeed very rare or there is another name for it?
And what I am very interested in finding out is about the mucinous feature of this lung cancer type since my sister's doctor emphasized the word "mucinous" multiple times. He said if it was not mucinous, the perspective would be very different. Does the "mucinous" feature alone make the recurrence more likely and survival rate a lot lower than other type of lung cancer?
She is scheduled to see an oncologist this week. I assume the doctor may order chemo as adjuvant treatment. I will get the update after her appointment.
I am trying to learn as many medical terms about lung cancer as possible, but it is very hard to understand the research papers out there.
Any advice, treatment experiece and knowledge sharing will be greatly appreciated.
