8 warning signs of cancer

Lumps, weight loss, bruising, changes in bowel habits, shortness of breath, persistent cough, unusual pain, or abnormal skin could signal cancer and require immediate examination.

A new survey reveals many individuals are delaying investigation of potential cancer symptoms, often due to difficulty securing general practitioner (GP) appointments or underestimating the severity of their health concerns.

A study by Cancer Research UK, which surveyed 6,844 individuals across the United Kingdom via YouGov, found that 53% anticipated difficulty booking GP appointments, 47% actually experienced problems, 44% believed their symptoms were not serious, and 43% thought they could manage the issues themselves.

Following these findings, Megan Winter, health information manager at Cancer Research UK, emphasized the wide range of cancer signs and symptoms, noting they can manifest differently in each person. Therefore, she advises listening to your body and speaking with your doctor if you notice anything unusual.

Here are 8 signs that always warrant professional evaluation:

Unusual Lumps or Swelling

If you notice any unusual lumps or swelling anywhere on your body, it is advisable to get them checked. For instance, a lump or swelling around the breast, below the elbow, and up to the collarbone could indicate potential breast cancer.

Unexplained Weight Loss or Fatigue

Some cancer symptoms can affect the entire body, leading to unexplained weight loss or fatigue.

Unexplained Bruising

Unexplained bruising can be another general symptom of cancer. For example, if you bruise more easily without injury, you should consult a doctor.

Changes in Bowel Habits

If you notice a change in your bowel habits, such as constipation or more frequent bowel movements than usual, you should discuss this with your general practitioner. Additionally, blood in your stool or urine, or unexplained vaginal bleeding between periods and after sex, also warrants investigation.

Shortness of Breath

If you experience shortness of breath during normal daily activities like housework, or if you have difficulty breathing without a clear reason, you need to see a doctor.

Persistent Cough

If you have a persistent cough that does not clear up within three weeks, or if your cough has changed or worsened, you should seek a proper diagnosis.

Unexplained Pain

As we age, experiencing aches and pains is common, but any unexplained or persistent pain anywhere in the body could be a warning sign of a more serious health issue.

Skin Changes

If you notice any skin changes, such as areas that do not heal, get them checked. A detailed list of specific symptoms for melanoma skin cancer can be found on the Cancer Research UK website.

It is crucial not to overlook these warning symptoms, as cancer diagnosed at an early stage, when it is small and has not spread, offers more treatment options and a greater likelihood of successful treatment.

“If you listen to your body and speak to your doctor about any changes, it can make all the difference in outcomes,” said Megan Winter, adding that in most cases, symptoms will not be cancer, but if they are, early detection makes a significant difference.
