Doctor William Li, a Harvard-trained physician, researcher, and author of "Eat To Beat Your Diet", states that the body provides signs when it is unwell. In a post shared on his website, Doctor Li discussed subtle indicators that something might be amiss in the body. However, most people tend to overlook minor changes until their condition worsens.

Here are 5 signs that demand your attention:

Blood in stool

According to Doctor Li, blood in stool is a sign you should not ignore. This is one of the most crucial indicators. It can be a symptom of serious issues such as colon cancer, anal cancer, or less severe problems like hemorrhoids or anal fissures.

"If you notice bright red blood, it is important to consult a doctor immediately, who will likely recommend a colonoscopy for further investigation", the doctor said. He noted that a colonoscopy is vital in identifying "pre-cancerous polyps" or other abnormalities in the digestive tract.

Blood in saliva

If you observe blood in your saliva, do not dismiss it. Doctor Li warns that it could be a potential warning sign of lung cancer or other cancers of the throat or mouth. "This type of bleeding can originate from abnormal blood vessels that supply cancerous tumors", he explained.

Most individuals dismiss bleeding as an injury from brushing teeth. However, Doctor Li emphasizes the importance of seeing a doctor if such a sign occurs, as early detection significantly increases the chances of successful treatment.

A recent study by the University of Basque Country found that saliva holds answers to many questions. It can reveal the risk of developing cancer, heart disease, or Parkinson's disease.

Blood in urine

Doctor Li advises prompt action if you notice blood in your urine. The doctor reminds us that blood in urine may indicate bladder or prostate cancer, especially for smokers or individuals exposed to industrial dyes. "Blood in urine can also point to infections such as hemorrhagic cystitis", the doctor stated.

According to the US National Institute of Diabetes and Digestive and Kidney Diseases, blood in urine can stem from various reasons, including infections or inflammation in the bladder or kidneys, injuries, bladder cancer, or even sickle cell disease. If you notice blood when urinating, it is important to schedule an appointment to rule out or address these conditions.

Blood on skin

If you notice blood on your skin without a cut, it is a red flag. According to Doctor Li, blood on the skin can be a potential sign of skin cancer, such as melanoma. "Look for elevated lesions, irregularly shaped ones that change color or size. These are important warning signs, and consulting a dermatologist for a thorough skin check is necessary", he advised.

Skin cancer is the most common type of cancer diagnosed worldwide. According to the WHO, an estimated 330,000 new melanoma cases were diagnosed in 2022, and nearly 60,000 people died from the disease. Early detection is crucial in such instances.

Vaginal bleeding

Another important sign requiring immediate medical attention is abnormal vaginal bleeding. Bleeding, particularly after menopause, can be a warning sign of cervical or uterine cancer.

"While menstrual bleeding is normal, any unusual spotting between cycles or postmenopausal bleeding should cause concern", Doctor Li said. He explained that bleeding can originate from tumors in the cervix or uterus, which, like other cancers, hijack blood supply, causing abnormal bleeding.

In such cases, it is important to consult a gynecologist immediately for a pelvic examination, ultrasound, and further tests to rule out any serious conditions.

These symptoms do not always indicate cancer but should never be ignored. They can aid in early disease detection, preventing dangerous complications.
