Hi @pb50, Thankfully research keeps coming up with new therapies. The molecular therapies are sometimes referred to targeted therapy. My cancer has one of the mutations that are 'targetable', so I take a targeted therapy (oral pills) that stops the cancer from forming.
These are unlike immunotherapies, where your immune system is programmed to attack the cancer cells.
"Targeted drug treatments focus on specific abnormalities present within cancer cells. By blocking these abnormalities, targeted drug treatments can cause cancer cells to die. Many targeted therapy drugs are used to treat lung cancer, though most are reserved for people with advanced or recurrent cancer.
Some targeted therapies only work in people whose cancer cells have certain genetic mutations. Your cancer cells may be tested in a laboratory to see if these drugs might help you." (https://www.mayoclinic.org/diseases-conditions/lung-cancer/diagnosis-treatment/drc-20374627)
