Cancer often has no specific symptoms, so it is important that people limit their risk factors and undergo appropriate cancer screening. Most cancer screening is specific to certain age groups and your primary care doctor will know what screening to perform depending on your age. People with risk factors for cancer (for example, smokers, heavy alcohol use, high sun exposure, genetics) should be acutely aware of potential cancer symptoms and be evaluated by a physician if any develop. The best way to fight cancers is by prevention (eliminating or decreasing risk factors) and early detection.
Consequently, individuals need to know which symptoms might point to cancer. People should not ignore a warning symptom that might lead to early diagnosis and possibly to a cure.
1. Persistent cough or blood-tinged saliva
– These symptoms usually represent simple infections such as bronchitis or sinusitis.
– They could be symptoms of cancer of the lung, head, and neck. Anyone with a nagging cough that lasts more than a month or with blood in the mucus that is coughed up should see a doctor.
