Symptoms of cancer

Cancer symptoms can vary greatly depending on where in the body the cancer originated.

Some types of cancer provide no symptoms in the early stages, while others can give very specific signs.

It is important to emphasize that most symptoms that could indicate cancer can also have other causes. However, it is always a good idea to contact your doctor if you experience persistent or unexplained symptoms.

Common symptoms of cancer

Unexplained weight loss

When you lose weight without changing your diet or exercise habits, it can be a sign of cancer.

Fatigue

A persistent feeling of tiredness that does not disappear with rest can be a symptom.

Fever and night sweats

These symptoms can occur when cancer affects the immune system.

Pain

Pain can be a late symptom of cancer and can vary greatly depending on where the cancer is located.

Skin changes

This can include itching, redness, sores that do not heal, or changes in moles.

Bleeding

Unexplained bleeding, e.g., from the nose, mouth, bowel, or vagina, can be a sign of cancer.

Cough or hoarseness

A persistent cough or changes in the voice can be signs of lung cancer or laryngeal cancer.

Difficulty swallowing

Difficulty swallowing can be a symptom of esophageal or throat cancer.

Changes in bowel habits

Constipation, diarrhea, or blood in the stool can be signs of colorectal cancer.

Lumps or swellings

A lump that can be felt, e.g., in the breast, neck, or groin, can be a sign of cancer.

The 7 signs of cancer

The Danish Cancer Society has developed a list of 7 signs that can be symptoms of cancer:

  • Persistent difficulty swallowing
  • Unexplained weight loss
  • Persistent cough or hoarseness
  • Altered bowel pattern
  • Unexplained bleeding
  • Changed moles or sores that do not heal
  • Lumps or swellings that change

Common types of cancer

The most common types of cancer vary slightly between men and women. Here is an overview of some of the most common forms:

In women

  • Breast cancer: This is the most frequently occurring type of cancer in women.
  • Lung cancer: Also a serious threat, especially in connection with smoking.
  • Colerectal cancer: Including colon and rectal cancer.
  • Melanoma: Important to monitor changes in moles.
  • Ovarian cancer: This type of cancer can be difficult to detect in early stages.

In men

General for both men and women

Note

Cancer is not one disease, but many different ones. Each type of cancer has its own characteristics, causes, and treatment options.

Early detection is crucial

Be aware of any symptoms. It will increase the chances of recovery. Accept the screening offers you receive.

Lifestyle matters

A healthy diet, regular exercise, and avoiding risk factors such as smoking can reduce the risk of developing cancer.

Important

It is important to emphasize that most people who experience these symptoms do not have cancer. But if you have questions, you should always contact your doctor for an assessment.
