It depends on what stage it is and whether it is benign or malignant. If it is a higher stage malignant cancer it has LW chances of survival.

Cancer cell feed only on carbs so the less u feed the less chance of growing. Idk why on earth doctors say abt it but their is this diet called keto diet wc is high fat and low carb diet. Idk abt lung cancer gin there are ppl who cured stage 4 cancer by a keto diet if u can afford nutritionist amakr . Good luck
