All testing on heart neg/cxr clear. Have chest pains and feel burning sensation chest area on and off. Is this a precursor to lung cancer?

No. Your symptoms most likely suggest some gastric reflux symptoms. Your chest xray is clear which is re-assuring. If you are a heavy smoker a ct scan for lung cancer screening may be appropriate;.
More likely heartbrn. Off and on burning sensation just beneath the middle or to the left of the breast bone is more often heartburn than anything else. Nicotine or caffeine intake, acidic foods, reclining with a full stomach, all can aggravate that process. Lung cancer is unlikely to give you this pattern of symptoms if it give any warning symptoms at all.

Should I take a full strength of chemo. When only 1/3 of the strength causes bad chest pain I have only about 15% of my heart and 20% of my kidney. I have lung cancer, the no cell cancer, with each treatment it has affected my heart. But if I don't take t

This . This is certainly a difficult situation. One of the most important thing to do when giving chemotherapy to a patient is safety. If you have heart and kidney problems and are also having bad chest pains when you get chemotherapy it may not be safe to continue to get the same full dose of chemotherapy. Furthermore, it may not be safe to keep giving you the same chemotherapy at all. Many times we are able to reduce the dose of chemotherapy without having an impact on how effective it is. Even if the chemotherapy has to be stopped and the cancer eventually grows back again, that is actually better than dying from a bad side effect from chemotherapy. Chemotherapy can be very dangerous in patients that are not fit enough to get it or in patients whose heart, kidneys, liver or bone marrows are not working well. In these cases it is better to stop or reduce the dose rather than giving full doses and harm the patient. You should talk to your doctor and express your concerns and symptoms. Together, you should be able to find a treatment that gets you the most benefit and the least side effects. Best regards, ariel. Read more...
It's a choice. Nobody can make this decision for you. It is important that you have an honest and open discussion with your cancer team. You will need to ask what are the reasonable expectations from treatment vs non-treatment? Ultimately, the question only you can answer, after thorough discussion with your team, "will treatment be worse then cancer? What quality of life can i expect after treatment?". Read more...

Male, 21.Er for chest pain. Had ekg, blood test and chest xrays. Everything came out normal. Doubt its my heart. Are xrays enough to rule out lung cancer?

For you - yes. The incidence of lung cancer for someone 21 years of age is essentially zero. I remember reading some where that the risk of a 30 y/o person dying from lung cancer over the next 10 years is 0. Chest xrays are an excellent screening tool. They will miss some small percentage of lesions because of size and/or location. The most important thing you can do is stop or never smoke. Read more...

Quit smoking. It is not likely that you have lung cancer, but lung symptoms are a strong reason, if you needed one, to quit smoking.

Stabbing chest pains, increased anxiety, history of depression, itching, 2 weeks smoke free? Blood urine heart chest X-ray all clear. Worrying?!

Chest pain. The likely answer is Anxiety mediated, but i do not know you, especially over the computer, so chest pain needs to be seen to rule out cardiac. If probable anxiety as suspected and you have an itch too, then Hydroxyzine HCL is non-addicting, and FDA approved for both anxiety and itching, so your Dr. may "kill 2 birds with one stone." Best wishes. Read more...
Hang on! Smoke-free for 2 weeks - that is AWESOME! Quitting smoking is probably the single best thing you could ever do for your health. But it's not easy and coming off the nicotine can increase anxiety while your body adjusts to making it's own neurotransmitters. Try taking some Claritin (loratadine) for the itching during the day and benedryl at night. See your doctor if the depression gets worse. Congrats!!! Read more...

Burning in chest (not pains) no reflux and my heart beats faster when I get this burning sensation. What could it be. Comes and goes.?

Often GI. This sounds like a gastrointestinal issue. This pain associated with shortness of breath, profuse sweating, dizziness, etc. would be concerning for a heart attack. It would be unusual, however the heart rate you describe might be an irregular heart rhythm triggering the chest discomfort. Talk with you doctor about an evaluation with a GI specialist and possibly a heart monitor. Read more...
