Lung cancer : Lung cancer can not be detected by a blood test. Ct scan and pet scan may be necessary to detect the current status of lung cancer.

Discuss...: Your question is not exactly clear. "remission" is a term used to describe cancer that was diagnosed and after treatment or in unusual cases "spontaneously" is no longer clinically present. The "blood tests" currently marketed are used to "find" (screen) cancer. Tests like "early cdt" are generally inaccurate if you have already had a cancer. Not used to diagnose "remission".

Provided original answer
Given limited space for primary answer, I wanted to add some additional information. The key is anyone at risk for cancer (presumably lung in this case), needs to discuss with their family physician and be referred to an appropriate multidisciplinary COMPREHENSIVE cancer screening program. If lung cancer, the individual should be referred to a COMPREHENSIVE thoracic surgical oncology program. If someone has been treated for lung cancer and told they are in "remission", the should be under the care of a multidisciplinary thoracic oncology program and having regular follow-ups and surveillance.

Is it ok to get a chest X-ray in the first trimester?

If necessary: Any type of test that exposes you to radiation (x-ray, cat scan) should generally be avoided in pregnancy. If such a test is medically necessary, the abdomen should be shielded with a lead apron to prevent exposure to the baby.
Dr. Christopher Powers
Obstetrics and Gynecology 23 years experience
In the first trimester, the uterus is still a pelvic organ, i.e., it still hasn't risen much above the pubic bone. Agree with adequate shielding, a chest xray will be no problem.

Will I be able to breastfeed if I have had a breast reduction?

5 doctor answers8 doctors weighed in
Dr. Robert Benner
Obstetrics and Gynecology 33 years experience
No: Most women who have had breast reductions will find it difficult to nurse, and some may find it impossible. There's no harm in trying but it is important to be realistic. The operation relocates the nipple and disrupts the nerves that signal the brain to produce and release breast milk when the baby sucks. Sometimes there is adequate nerve function and with persistence nursing can succeed.

Whats it mean when a woman urinates blood and has sharp pains on the side above hips?

Many causes: The most common thing is a bladder infection but there are other causes like a kidney stone (should hurt) or something in the bladder like polyps or other growths. Some bladder conditions like interstitial cystitis can bleed. See a doctor for the right diagnosis as this could be something important. Always get sharp pain checked out as well. Thats our body telling us something is not right.
A member asked:

Chronic wind causing pain in chest and down both arms.?

1 doctor answer3 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
Doctor can evaluate: Is chronic wind the stomach gas & bloating, with a need to burp? Or, is chronic wind the intestinal gas, with a need to pass gas via the anus (fart)? Stomach gas and heartburn (reflux) can cause chest pains. Chest pains can also be spasms in the esophagus or angina pain (as in heart attack pain). The aorta is also in the chest. Pains going down the arms can also be effects on spinal cord nerves.
