Can benign tumors cause problems?

Benign tumors are not usually problematic. However, they can become large and compress structures nearby, causing pain or other medical complications. For example, a large benign lung tumor could compress the trachea (windpipe) and cause difficulty in breathing.

What health problems do benign tumors cause?

Noncancerous moles or colon polyps, for example, can turn into cancer at a later time. Some types of internal benign tumors may cause other problems. Uterine fibroids can cause pelvic pain and abnormal bleeding, and some internal tumors may restrict a blood vessel or cause pain by pressing on a nerve.

What happens if a benign tumor is left untreated?

Meningiomas: Meningiomas are common and originate in the central nervous system, which contains the brain and spinal cord. Though benign, they create serious symptoms, including headaches, speech problems and seizures, and they can even become fatal if untreated.

Should you worry about benign tumors?

Even though most benign tumors are harmless and can be left alone, it’s important they be monitored. And any tumor that is painful or growing requires a visit to the doctor.

Are benign tumors bad?

A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can. In most cases, the outlook with benign tumors is very good. But benign tumors can be serious if they press on vital structures such as blood vessels or nerves.

Can you tell a tumor is benign without a biopsy?

Benign tumors can grow but do not spread. There is no way to tell from symptoms alone if a tumor is benign or malignant. Often an MRI scan can reveal the tumor type, but in many cases, a biopsy is required. If you are diagnosed with a benign brain tumor, you’re not alone.

What are characteristics of benign tumors?

Benign tumors aren’t cancerous. They won’t invade surrounding tissue or spread elsewhere. Even so, they can cause serious problems when they grow near vital organs, press on a nerve, or restrict blood flow. Benign tumors usually respond well to treatment.

Should benign tumors be removed?

Benign tumors don’t have cancer cells, but they can still be dangerous and need to be removed. That’s because some tumors can grow large enough to block the pathway of important nutrients or put pressure on critical organs.

Does a benign tumor spread?

Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders.

Can an MRI tell if a tumor is benign?

MRI is a well-established tool for the detection and local staging of soft-tissue tumours. However, its ability to differentiate between benign and malignant soft-tissue lesions has been found to vary widely [6-8,10-12].

Can benign tumors cause death?

Benign tumors generally do not cause death or serious illness unless they are very large, such as some benign ovarian tumors, or if they affect a critical organ that makes it difficult to operate on and remove them, such as tumors in the brain.

How big can benign tumors get?

These tumours can grow to 5 to 10 cm in diameter.

Can benign lymphoma spread?

Benign lymphoma is very rarely life-threatening and the tumors (or lumps) are usually fairly slow-growing and rarely expand enough to involve any tissue or other body parts.

How do you shrink a benign tumor?

Conventional chemotherapy is occasionally used to shrink non-cancerous brain tumours or kill any cells left behind after surgery. Radiotherapy involves using controlled doses of high-energy radiation, usually X-rays, to kill the tumour cells. Chemotherapy is less frequently used to treat non-cancerous brain tumours.

Can a benign tumor come back after surgery?

It will not usually come back if all of the tumour can be safely removed during surgery. If the tumour cannot be completely removed, there’s a risk it could grow back. In this case it’ll be closely monitored using scans or treated with radiotherapy. Read about malignant brain tumour (brain cancer).

Can a CT scan tell if a tumor is benign?

A CT scan can be wrong: it can’t tell the difference between cancerous tissue and non-cancerous tissue.
