Because lungs are vital for people's survival, if they are affected in some way like having a tumour inside affects the quality of life and the patient experiences short breath and difficulty breathing. If the tumour is big in size and it is removed, the surgeon is also forced to cut a part of the lung, a big part around the tumour, so it's very difficult to treat this kind of cancer. Treatment includes surgery , chemotherapy, radiotherapy and laser therapy.

Chemotherapy is that kind of treatment that deals with the drugs used for lung cancer. It is a systemic treatment, that is it uses medication to try to kill the cancer cells all over the body, not only locally. That is why it is used in stages three and four of cancer. There is no miraculous potion or recipe to use for all patients , but each has their own medication, a drug coktail prescribed by the oncologist doctor depending on the stage of the cancer when it was diagnosed, the reaction of the tumour and of the whole body to medication and , of course, on the patient's tolerance of certain drugs.

There are lots of different types of drugs used for lung cancer and if you are curious you can find really comprehensive lists available on the internet.
