Have you ever heard that vaccines cause autism? If so why such thought persist? Hi my new friends! Hope you are all in good health! Have you ever heard that vaccines cause autism? If so why such thought persist? I look forward to reading all of your answers tomorrow.A. Yes I heard about that and avoided being injected sometimes.

Q. Can lung cancer be diagnosed on behalf of persistent cough? My father is a heavy smoker. He smoked for all his adult life and he never stopped. In the last few weeks he started to have persistent cough attacks. Can those attacks be the first sign of lung cancer?A. Smoking can damage the lung in many ways. The fact that someone that is a smoker is suffering from chronic cough doesn't mean that he is suffering from lung cancer.

Examples of primary headaches are migraine headaches, tension headaches, and cluster headaches. Secondary headaches are caused by associated disease. The associated disease may be minor or serious and life threatening. Tension headaches are the most common type of primary headache. Tension headaches are more common among women than men. Migraine headaches are the second most common type of primary headache. Secondary headaches have diverse causes, ranging from serious and life threatening conditions such as brain tumors, strokes, meningitis, and subarachnoid hemorrhages to less serious but common conditions such as withdrawal from caffeine and discontinuation of analgesics. http://www.medicinenet.com/headache/article.htm In any case if your headache continues you should see your doctor immediately.
