Treating early breast cancer

A number of treatments are available for early breast cancer. These include surgery, radiotherapy and a range of drug treatments. These are often used one after another rather than all at the same time.

You shouldn’t have to wait longer than one month for treatment after being diagnosed with breast cancer.


For most people with breast cancer, surgery happens before any other treatment, although some women will have other treatments beforehand. During surgery, cancerous tissue in the breast is removed. Surgeons also look to see whether lymph nodes (glands) in the armpit have been affected. If they have, these are removed too.

Many women have a process called breast conserving surgery (also called wide local excision or lumpectomy). This is where only the breast cancer and a small margin of healthy tissue is removed, but surrounding healthy breast tissue is not removed.

Some women, however, will need to have the whole breast removed in an operation known as a mastectomy. Women who are offered a mastectomy should also be offered breast construction (plastic surgery to rebuild the breast).

Women who do not have immediate reconstruction, or who choose not to have reconstruction at all, should be offered an appointment with a prosthesis fitting service (breast prostheses are artificial breasts).

Side effects of surgery may include:

  • pain and discomfort
  • infection
  • the collection of fluid in the wound area, causing swelling (seroma)
  • long-term swelling of your arm or nearby areas (lymphoedema)

Treatments are available to help relieve or reduce these side effects.

Your surgeon will explain to you the best approach to surgery in your case, and will help you to make any decisions you may have.

Planning your treatment

For more information about planning your treatment, such as tailoring your treatment and receptor tests, please see our best treatment guide if you're in England or Wales, or if you are in Scotland, our guide to breast cancer treatment in Scotland.


Radiotherapy is treatment with radiation (high energy X-rays). It is usually given after surgery and aims to destroy any cancer cells remaining after surgery.

Radiotherapy is usually recommended for women who have undergone a lumpectomy or sometimes a mastectomy. It is usually given to the affected breast or the area behind where the breast was removed. The lymph glands in the armpit and above the collarbone are also sometimes treated.

Before you have radiotherapy, your oncologist will work out exactly where to point the X-ray’s beams and what dose to use so that cancer cells are destroyed with minimum damage to normal tissues. A typical course of radiotherapy for breast cancer is given five days a week for three weeks. Each session lasts a few minutes.

Side effects of radiotherapy are generally short-lived. They may include:

  • Reddening of the skin treated
  • Possible burning (like a strong sunburn) to the area treated
  • Tiredness

Few women experience long-term side effects. These can, however, include:

  • Changes to the skin, bone, lung or heart near the area treated
  • Long-term swelling of your arm or nearby areas (lymphoedema)

Chemotherapy is treatment with one or more anti-cancer (cytotoxic) drugs. It aims to prevent the breast cancer spreading or coming back. Chemotherapy drugs are usually given directly into your bloodstream – either by injection directly into a vein or through a drip into a vein over a period of minutes or hours (an infusion). Chemotherapy is usually given after surgery, although some women have it before surgery.

Whether or not you are recommended to have chemotherapy will depend on a number of factors, including the grade of your breast cancer. There are several different chemotherapy drugs and a course of treatment generally combines two or three of these. A chemotherapy course is made up of repeated cycles of treatment, usually a few weeks apart, over several months.

Chemotherapy drugs circulate throughout the body. As well as cancer cells, they affect healthy body cells too – this causes side effects.

Most women suffer some short-term side-effects with chemotherapy treatment, although these vary a great deal.

Common side effects of chemotherapy include:

  • tiredness
  • nausea
  • vomiting
  • a sore mouth
  • mouth ulcers
  • muscle and joint aches
  • diarrhoea
  • hair loss (anything from slight to complete)
  • weight gain
  • menopausal symptoms

Remember, though, that a lot can be done to help relieve side effects, so if you do experience any of these, tell your oncologist or breast care nurse. For details of different chemotherapy drugs, including side effects, visit Cancer Research UK's website

Hormone therapies

Hormones are naturally occurring substances that control the growth and activity of cells in the body. However, the female hormones oestrogen and progesterone can also promote the growth of some breast cancers. Around three out of four breast cancers are sensitive to hormones in this way – these are known as hormone positive breast cancers.

Hormone therapies are tablets that block the production of female hormones or reduce the ability of breast cancer cells to respond to the hormones. They aim to prevent the breast cancer spreading or coming back.

They are only effective in treating breast cancers that are hormone positive (shown using receptor tests). All patients with hormone positive breast cancer should be offered hormone therapy, unless there is a reason this would be unsuitable.

The two types of hormone therapy are:

The exact treatment will vary from person to person, and is typically five or more years in length.

Tamoxifen and aromatase inhibitors can cause menopausal symptoms. Aromatase inhibitors can also cause pain and stiffness and osteoporosis. If you are suffering from severe side effects, we recommend you discuss this with your breast care team or GP.

Targeted (biological) therapy

Targeted therapies attack cancer cells directly (ie target them). They do not usually affect healthy tissues and so do not cause side effects such as sickness and hair loss.

Herceptin (also known as trastuzumab) is the targeted therapy available to treat early breast cancer. It aims to prevent the breast cancer spreading or coming back.

Herceptin targets breast cancers that express high levels of a protein called HER2. These breast cancers are known as HER2 positive breast cancers (shown using receptor tests) and account for around one in five breast cancers. Patients with HER2 negative cancers (those with low levels of HER2) do not benefit from Herceptin.

Women taking Herceptin may experience some side-effects including flu-like symptoms, and it can lead to heart problems. Due to this risk, Herceptin may not be a suitable treatment for everyone and all patients should have their heart function assessed before and during treatment.
