Cancer is a scary word but it’s important to take note of the symptoms. If detected early, cancer can be treated successfully. Many people are aware of some of the more commonly recognized symptoms of cancer, such as a new lump or an unusual mole.

However, some symptoms may be less apparent, making it easier for them to be overlooked or attributed to something else.

Unexplained weight loss

If you’re losing weight without trying, this may be a symptom of cancer. This is because cancer cells use up much of the body’s energy supply and can cause a reduction in appetite.

Fatigue

Though fatigue could be an indication of other illnesses, it could also be a warning sign of cancer. Cancer cells cause fatigue by releasing toxins into the body, leading to anemia, or causing the body to produce more hormones than necessary.

Persistent cough

If you’re experiencing a persistent cough, a hoarse voice, or have had a change in your cough pattern that has lasted longer than three weeks, it’s important to see your doctor.

While coughs are common and can be a symptom of other conditions such as respiratory infections, it could indicate something more serious such as lung cancer.

Bloating and indigestion

Many people experience bloating and indigestion and don’t think much of it.

However, it’s important to note these symptoms because they can also be symptoms of ovarian cancer, particularly if they have persisted for an extended period of time.

Changes in skin moles

While most people know that new moles could suggest potential skin problems like cancer, it’s important to also keep an eye on existing moles, particularly if they begin to change.

Changes in size, shape, color, or texture can all suggest that a mole might be cancerous.

Unusual bleeding

Unusual bleeding can be a symptom of cancer and applies to both men and women. For example, unusual bleeding could be bleeding outside of menstrual cycles or bleeding from the rectum.

It’s important to be aware of this symptom and speak to your doctor if you’re experiencing it.

Persistent headaches

Most headaches resolve themselves without problem. However, if headaches become persistent or are accompanied by vomiting, vision problems or other unusual symptoms, it’s important to get them checked out.

These could be early indications of brain tumors or other types of cancer.

Difficulty swallowing

Difficulty swallowing could be the sign of many things and, although it may seem minor, it’s important to have it checked out by a doctor. It could be an early warning sign of throat or esophageal cancer.

Pain

New or persistent pain can be a sign of cancer, particularly pain that doesn’t have a particular cause or location. For example, pain in a particular bone could signify metastatic cancer, where cancer has spread beyond the initial site.

Changes in bowel habits

It’s normal for bowel habits to fluctuate; however, if you’ve noticed significant changes for an extended period of time, it’s important to speak with your doctor.

Changes in bowel habits could be the result of colon or rectal cancer, and the earlier it’s detected, the better the chance of successful treatment.
