What's the symptoms of lung cancer?

I am not a doctor or nurse, so my answer is only from personal experience. Lung cancer is one of the worst and fastest as far as being terminal. There is no cure(Dear God, I wish there were) I am not knowledgable enough to answer your? about an 80 year old man but I promise to keep him in my prayers.

Take a look at ( http://www.all-about-cancer.us ) There is a lot of good content and information there. Good luck.

some symptoms are chronic cough, coughing up blood, weight loss, difficulty breathing...ct scans are almost always accurate...there are a lot of dangers at his age in trying to cure it..but the doctor will evaluate him, his currant condition and make the best decision for him.

Lung cancer is usually found somewhere else before it is found in the lung(s). Often there are no signs until then. Yes a CT scan can tell.The only way to cure it permanently is to beat it. If an 80 year old wishes to fight it then please do. The decision is that persons to make.

I do not know about the CT Scan, but I do know he can be helped by natural means, but it is not a quick fix, as it took time for him to get the cancer, but there is help. We have helped people who the doctors have given up on. Some of the things you can do is get him right off sugar and sugary, syropy foods. Also off acidity foods, onto alkalade foods. As most people have too much acid in their bodies which breeds the cancer and sugar feeds cancer. You probably got all kinds of chemicals in the house with the cleaning supples, which also can cause cancer. Get in touch with me and I will send you the foods he can have and the ones he should not have.

Breathlessness. Actually I don't know about cancer but I do know about Emphysema. Which my dad had. That's caused from smoking, being exposed to burning rubber, for tyres, my dad was a supervisor at Dunlop Tyre Factory - for those in Melbourne - at Montague - and my ex father-in-law smoking and being a cane train driver smelling smoke from the 'Cane Fields' in Mackay, Qld.

If the CT scan showed it then yeah they are pretty accurate, I would say physical symptoms would be re-current resp. infections, difficulty in breathing, removing the lung or a lobe may be an alternative but you said the patient is 80, the surgery would probably kill the patient, any surgery at this age is risky, the chances for developing pneumonia is great. and when you are talking about removing a lung that would be devastating, you may opt for chemo and radiation to prolong life but given the patients age, the quality of life will diminish, chemo and radiation make you very weak and sick, have you talked to the person? maybe you can talk to someone from hospice, If it was me or a relative I would try to spend time with them help them prepare and finish up wills etc. when you live to 80 that has been a good life, you may get a couple months or a couple of years, But any doctor that would suggest surgery at this age is only trying to milk medicare out of dollars. I wish you good luck.
