When Should You See a Doctor?

Not every symptom means cancer, but if you notice something unusual that lasts more than a couple of weeks, it’s best to consult your doctor. Early cancer detection can dramatically improve treatment outcomes and survival rates. According to the World Health Organization, early diagnosis plays a key role in preventing cancer-related deaths.
