List of terms beginning with Lo


A section of an organ. There are lobes of the brain, thyroid, liver and lungs. The right lung has three lobes and the left only two.


An operation to remove a lobe of an organ, for example, to remove a lobe of a lung.

Lobular carcinoma in situ

Lobular cancer in situ is also called LCIS. It means that there are cell changes inside the lining of the breast lobes. This is not cancer. But having LCIS means that you have an increased risk of getting breast cancer in the future. Even so, most women with LCIS will not get breast cancer.

Local anaesthetic

A medicine to numb a small part or area of the body so that you can’t feel anything. Some types are rubbed on to the skin and some are injected.

Local recurrence

When a cancer comes back in the same part of the body as the original cancer.

Local resection

A small operation to remove an early cancer which has not spread away from where it started growing.

Local spread

Local spread is also called local invasion. It means growth of a cancer into the area of the body around where it started.

Local treatment

A treatment that treats one area of the body. Surgery and radiotherapy are both local treatments. Also known as localised treatment.

Localised cancer

This means that a cancer involves only the area of the body where it started and the tissues next to it. For example, a localised bone cancer is only found in the bone in which it developed and possibly in muscle or tendon next to it.

Locally advanced cancer

Cancer that has spread from where it started into nearby body tissues or lymph nodes, but has not spread to other areas of the body.

Long term side effects

Unwanted effects of treatment that last for a long time after treatment has finished or may be permanent. With radiotherapy treatment, long term side effects may not appear until some time after treatment has finished (in some cases, several years).

Loop diathermy

Loop diathermy is a treatment for women with abnormal cells on the neck of the womb (cervix). It involves using a thin loop of electrified wire to remove the abnormal cells. This procedure is also known as a large loop excision of the transformation zone (LLETZ).

Low blood count

Lower than normal levels of red or white blood cells, or platelets. The numbers of blood cells is checked by a blood test.

Low density lipoproteins

Type of fats found in the blood. Cholesterol is a lipoprotein that can be high or low density.

Low grade lymphomas

Low grade lymphomas are slow growing and may not cause symptoms for a long time. They are usually treated with mild chemotherapy. Although it is difficult to cure them completely, they can often be kept under control for many years.

Low grade solid tumours

Means that the cells in the tumour look quite similar to normal cells. So the cancer may grow slowly and is not so likely to spread as a high grade cancer.

Low malignant potential

Means that a tumour is not likely to spread or grow quickly. In other words, a low grade cancer.
