“Most benign tumors aren't life-threatening. They can be left alone as they are unlikely to cause damage to any other areas of your body. In fact, many individuals carry benign tumors that don't require treatment, such as moles, throughout their lives.”
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.
While many benign tumors do not need treatment, some do, especially if they are causing symptoms. Usually if a benign tumor requires treatment, we remove it surgically. Whenever possible, we use minimally invasive techniques, which require small incisions and have minimal recovery time.
Non-cancerous brain tumours tend to stay in one place and don't spread. They won't usually come back if all of the tumour can be safely removed during surgery. Because they aren't cancerous they can often be successfully treated, but they're still serious and can be life threatening.
Some benign tumors can become cancerous over time (for example, in your colon or skin). If you have a benign neoplasm, a healthcare provider should monitor it regularly.
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.
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.
Benign tumors usually don't grow back.
The exact cause of a benign tumor is often unknown. It develops when cells in the body divide and grow at an excessive rate. Typically, the body is able to balance cell growth and division. When old or damaged cells die, they are automatically replaced with new, healthy cells.
When a benign tumor requires treatment, it isn't too different from the treatment of a malignant or cancerous tumor. It may be radiation therapy, radiosurgery for benign tumors located in the skull base, surgery or chemotherapy.
Benign (non-cancerous) brain tumours can usually be successfully removed with surgery and do not usually grow back. It often depends on whether the surgeon is able to safely remove all of the tumour. If there's some left, it can either be monitored with scans or treated with radiotherapy.
If not removed entirely by surgery, the growth of benign tumors should be monitored regularly by the patient and every six months to a year by the physician. In cases of sarcoma (cancerous growth), patients should have regular rechecks of their condition to monitor whether the cancer has metastasized or recurred.
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.
Benign tumors, while sometimes painful and potentially dangerous, do not pose the threat that malignant tumors do. "Malignant cells are more likely to metastasize [invade other organs]," says Fernando U. Garcia, MD, Pathologist at our hospital in Philadelphia.
Some forms of benign tumors may be harmful to health. Benign tumor growth causes a mass effect that can compress neighboring tissues. This can lead to nerve damage, blood flow reduction (ischemia), tissue death (necrosis), or organ damage.
2 While benign tumors are not cancerous, some of them can grow very large (sometimes up to several pounds) if left untreated.
Benign and cancerous (malignant) tumours
Tumours (lumps) can be benign or cancerous (malignant). Benign means it is not cancer. Benign tumours: usually grow quite slowly.
Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain. Tumors are made up of extra cells.
Cysts that appear uniform after examination by ultrasound or a computerized tomography (CT) scan are almost always benign and should simply be observed. If the cyst has solid components, it may be benign or malignant and should have further evaluation.
Most patients are able to resume normal activity levels and return to work in six to 12 weeks.
Doctors may soon be able to use a blood test to distinguish between benign and cancerous tumors in people with NF1. People with an inherited condition known as neurofibromatosis type 1, or NF1, often develop non-cancerous, or benign, tumors that grow along nerves.
Even benign tumors can be uncomfortable. If you feel or see a lump, visit an oncologist for an examination. If the doctor confirms that you have a malignant tumor, you will likely feel some uncertainty and fear. However, you can have peace of mind that the doctor will develop an effective treatment plan.
In clinical work, imaging technologies are generally used to identify lung metastasis; however, it is difficult to distinguish malignant from benign pulmonary nodules in some patients. Thus, some benign lung nodules are misdiagnosed as lung metastases, resulting in incorrect clinical staging and treatment.
Lumps that could be cancer might be found by imaging tests or felt as lumps during a physical exam, but they still must be sampled and looked at under a microscope to find out what they really are. Not all lumps are cancer. In fact, most tumors are not cancer.
A benign neoplasm looks a lot like the tissue with normal cells from which it originated, and has a slow growth rate. Benign neoplasms do not invade surrounding tissues and they do not metastasize. Thus, characteristics include: Slow growth.
