Sometimes, it’s possible to find cancer before having symptoms. The American Cancer Society and other health groups recommend cancer-related check-ups and certain tests for people even though they have no symptoms. This helps find certain cancers early, before symptoms start. For more information on early detection tests, see our document called American Cancer Society Guidelines for the Early Detection of Cancer . But keep in mind, even if you have these recommended tests, it’s still important to see a doctor if you have any symptoms.
Low blood pressure readings in healthy subjects without symptoms or organ damage need no treatment. All patients with symptoms possibly due to low blood pressure should be evaluated by a doctor. Patients who have had a major drop in blood pressure from their usual levels even without the development of symptoms also should be evaluated. The doctor needs to identify the cause of the low blood pressure; remedies will depend on the cause. For example, if a medication is causing the low blood pressure, the dose of medication may have to be reduced or the medication stopped. Do not adjust medication dose on your own, and do not stop taking any medication without first consulting your doctor.
