Stage 2 breast cancer

Stage 2 breast cancer means that the cancer is either in the breast or in the nearby lymph nodes or both. It is an early stage breast cancer.

The stage of a cancer tells you how big it is and how far it has spread. It helps your doctor decide the best treatment for you. There are different systems used in the UK to stage breast cancer. Stage 2 is part of the number staging system. Doctors may also use the TNM staging system.  

Staging for breast cancer is very complex. Many different factors are considered before doctors can confirm your final stage. Speak to your doctor or breast cancer nurse specialist if you have any questions about your staging.

Stage 2 can be divided into 2A and 2B. Below is a simplified description of stage 2A and 2B breast cancer.

Treatment

The number staging helps your doctor decide which treatment you need. Treatment also depends on:

• the type of cells the cancer started in

• whether your cancer cells have receptors for particular cancer drugs

• the grade of the cancer 

• whether you have had the ​menopause​   

• other health conditions you may have

Your doctor will take many different factors into account when deciding which treatment is best for you.

Surgery is usually one of the main treatments for stage 2 breast cancer. You may also have drug treatments such as chemotherapy and hormone therapy as a first treatment. This is called neo adjuvant treatment. You then have surgery.   

Surgery

Your surgeon might remove the cancer and a border of normal breast tissue. This is called breast conserving surgery or a wide local excision. After breast conserving surgery, you might have radiotherapy to the rest of the breast.

Or you might have the whole breast removed. This is called a mastectomy. You can then choose to have a new breast made (breast reconstruction). You might also have radiotherapy to the chest wall after having a mastectomy.

Checking the lymph nodes

Before your surgery, you have an ultrasound scan to check the lymph nodes in the armpit (axilla). This is to see if they contain cancer cells. If breast cancer spreads, it usually first spreads to the lymph nodes close to the breast.

Depending on the results of your scan you might have:

• a ​sentinel lymph node​ biopsy during your breast cancer operation

• surgery to remove the lymph nodes under your arm
