Our body often gives us a number of signals. By this, for example, it tells us that we are not healthy and we must act immediately. Our body can signal cancer to us in up to ten ways.

What are these signals?

There are 10 in total. Find out which signs they are.

1. Lumps or swellings

Any strange lumps are best checked by a doctor. According to the survey, 7.5% of people reported unexplained lumps. Although 67% of them visited their doctor, 77% did not think it would be serious.

2. Cough / hoarseness

It is the season of colds and flu, so a cough may seem perfectly normal. However, if a cough persists, it may indicate problems with the larynx, lungs, or thyroid. This was the most common symptom among study participants. “We know that coughs and colds are ubiquitous nowadays, and therefore we do not recommend that everyone who coughs should go to the doctor immediately,” says Whitaker. “However, if you have symptoms that do not go away or are unusual, do not hesitate to contact your doctor.”

3. Changes in bowel habits

The study found that 18% of people experienced changes in the timing, volume, and size of stools. Although these changes are usually caused by certain foods or medications, if they occur too often, they may be a sign of colon cancer.

4. Changes in urinary activity

Because urinary tract infections are common in women, this symptom is often overlooked and mistakenly assumed to be a urinary infection. Whether you are male or female, if you notice blood in your urine, have a frequent urge to urinate, or experience pain during bowel movements, be sure to see a doctor to rule out urinary tract cancer, kidney cancer, or prostate cancer.

5. Unexplained persistent pain

Persistent pain is how your body signals a problem. It can be anything from bone cancer to ovarian cancer. According to the American Cancer Society, pain in cancer usually means that the cancer is spreading. And that is a good reason to make an appointment with your doctor. One surprising finding of the above-mentioned study is that only about 35% of people in the study believed that pain could be a serious problem.

6. Persistent sore throat

A sore throat can be a sign of winter weather, but a persistent sore may mean something much worse, such as laryngeal or throat cancer. Almost 78% of survey respondents do not think that a sore throat is a serious symptom.

7. Unexplained weight loss

According to the American Association for Cancer Research, unexplained weight loss of 5 kg or more can be the first sign of cancer. This warning sign is common in people who have pancreatic, stomach, lung, or esophageal cancer.

8. Difficulty swallowing

A tightness in the throat, although not a common symptom in this test, can be a problem of the nervous or immune system or a symptom of various diseases, including esophageal, stomach, or throat cancer. This is something to watch for.

9. Bleeding

Coughing up blood can be a sign of lung cancer and blood in the stool can be a sign of bowel or rectal cancer. Women who experience unexplained vaginal bleeding should be examined for cervical cancer. A flow of blood from the nipple may indicate breast cancer, while blood in the urine may indicate urinary tract or kidney cancer. Unusual bleeding can occur at various stages of cancer and should be reported to a doctor.

10. Various changes in moles

Of the 7% of respondents who reported a change in the appearance of a mole, freckle, or wart, only 47% consulted their doctor. Even more troubling is that more than 88% of respondents do not think it is a serious symptom, even though it could be a sign of skin cancer, which is mostly treatable.
