I have a thin black vertical line along my entire fingernail that grows after trimming it, but doesn't change in width. Could this be cancer?

See a dermatologist: You need to visit a dermatologist to evaluate the area. It could be blood underneath your nail cause by trauma when trimming the nails or fungus. You may need a biopsy of the nail to make sure that this is not a melanoma. This is the most deadly of all the skin cancers.

I have clubbed fingernails and emphysema. My dr. Saw spots on my lungs. Could it be cancer?

I have clubbed fingernails and emphysema. My dr. Saw spots on my lungs. Could it be cancer?

Possibly: Clubbing can be related to many pulmonary conditions, including emphysema and cancer. What is obviously concerning is that your doctor saw 'spots' on your lungs (by an xray I would presume). You need to make sure that you are scheduled for further work up soon. And you need to STOP SMOKING! It's the best thing you can do for your body.

I have all the symptoms of lung cancer: shortness of breath, cough with yellow phlegm and occasional red streaks, fingernail clubbing...but my Chest X-Ray and Noncontrast High-Res Chest CT were negative. Doctors are saying I'm fine, but I'm scared?

I have all the symptoms of lung cancer: shortness of breath, cough with yellow phlegm and occasional red streaks, fingernail clubbing...but my Chest X-Ray and Noncontrast High-Res Chest CT were negative. Doctors are saying I'm fine, but I'm scared?

Trust your physician: Or obtain a pulmonary medical consultation as a second opinion. Without symptoms such as weight loss. Anorexia, expectorating pure blood. Chronic spasmodic coughing, etc. This is not consistent with lung cancer, especially with a negative CT scan. I suggest behavioral counseling with a certified psychotherpist for CBT.

Is line on my sons finger nail cancer?

Probably not: Nail cancer is very unusual. Is the line on all of the nails? If such is the case and depending on the appearance, it may suggest a metabolic abnormality. At any rate, if it is a concern, its best to have it examined by your pediatrician.

My middle finger nail I noticed I have 2 red streaks that are straight and covers full nail length. Appears to be under a ridges. Cancer?

Doubtful: Occasionally melanoma can present with a black streak. This doesn't sound like a classic presentation for cancer but your dermatologist can likely provide an accurate assessment. Take care.

If you get regular screenings, such as a pap smear, mammogram, colonoscopy after 50, regular health check ups, skin surveys, oral cancer evaluarions, and the like, and be alert for signs of illness, your doctor should be able to detect any abnormality early enough to intervene.
