Breast cancer starts when cells in the breast begin to divide and grow in an abnormal way.
Tubular breast cancer is a type of invasive breast cancer. This means that cancer cells have the potential to spread to other parts of the body. However it is less likely to spread than with other types of breast cancer.
It’s called tubular breast cancer because the cancer cells form tube-shaped structures when looked at under a microscope. It’s most common in women over 50, although you can get it at any age. It’s very rare in men.
Tubular breast cancer accounts for between 5 and 10% of all breast cancers. It’s often found alongside other types of breast cancer.
Generally, tubular breast cancer has a very good prognosis (outlook) following treatment. This is because the cells are nearly always low grade and slow growing. Grade is the system used to classify cancer cells according to how different they are to normal breast cells and how quickly they’re growing.
The outlook is particularly good if the cancer is ‘pure’ tubular, which means it’s not mixed with other types of breast cancer.
Most tubular breast cancers are found during routine breast screening although can also be diagnosed following referral to a breast clinic.
Tubular breast cancer is diagnosed using a number of tests. These include:
For more information about these tests, read about what to expect at a breast clinic appointment.
Treatment aims to remove the cancer and reduce the risk of it coming back or spreading to other parts of the body.
Surgery is usually the first treatment for tubular breast cancer.
There are two main types of breast surgery:
The type of surgery that is recommended depends on the area of the breast affected, the size of the cancer relative to the size of your breast and whether more than one area in the breast is affected. Your breast surgeon will discuss this with you.
Sometimes more surgery is needed if the margin of normal tissue surrounding the cancer that was removed during the first operation is not clear. This is to ensure that all the cancer has been removed. In some cases, this second operation will be a mastectomy.
If you’re going to have a mastectomy, you’ll usually be given the option of having breast reconstruction. This can be done at the same time as your mastectomy (immediate reconstruction) or months or years later (delayed reconstruction).
Surgery to the lymph nodes
Tubular breast cancer is less likely to spread to the lymph nodes (glands) under the arm than most other types of breast cancer. However, your specialist team will want to check if your lymph nodes have been affected. This helps them decide whether you will benefit from any additional treatment after surgery. To do this, your surgeon is likely to recommend an operation to remove either some of the lymph nodes (a lymph node sample or biopsy) or all of them (a lymph node clearance).
Sentinel lymph node biopsy is widely used if tests before surgery show no evidence of the lymph nodes containing cancer cells. It identifies whether the first lymph node (or nodes) is clear of cancer cells. If it is, this usually means the other nodes are clear too, so no more will need to be removed. Sentinel lymph node biopsy is usually carried out at the same time as your cancer surgery but may be done before your surgery.
If the results of the sentinel lymph node biopsy show that the first node or nodes are affected, more surgery or radiotherapy to the remaining lymph nodes may be recommended.

Adjuvant (additional) treatments
After surgery, you may need further treatments. These are called adjuvant treatments and can include:
The aim of these treatments is to reduce the risk of breast cancer returning in the same breast or developing in the other breast, or spreading somewhere else in the body.
Radiotherapy uses high energy x-rays to destroy cancer cells.
If you have breast-conserving surgery, you’ll usually be offered radiotherapy to reduce the risk of cancer coming back in the same breast. Sometimes you may be offered radiotherapy to the nodes under your arm.
Radiotherapy may sometimes be given after a mastectomy, for example when several lymph nodes under the arm contain cancer cells, but this is unlikely with tubular breast cancer.
Hormone (endocrine) therapy
The hormone oestrogen can stimulate some breast cancers to grow. A number of hormone therapies work in different ways to block the effect of oestrogen on cancer cells.
Hormone therapy will only be prescribed if your breast cancer has receptors within the cell that bind to oestrogen, known as oestrogen receptor positive or ER+ breast cancer.
All breast cancers are tested for oestrogen receptors using tissue from a biopsy or after surgery. If your cancer is oestrogen receptor positive, your specialist will discuss with you which hormone therapy they think is most appropriate. Tubular breast cancers are usually oestrogen receptor positive.
Chemotherapy destroys cancer cells using anti-cancer drugs. It is given to reduce the risk of breast cancer returning.
People diagnosed with tubular breast cancer don’t usually have chemotherapy. This is because tubular breast cancer is almost always low grade and much less likely than some other types of breast cancer to spread to other areas of the body. However, it may be recommended for some people.
Whether you’re offered chemotherapy depends on various features of the cancer. Factors that will be considered include its size, its grade and whether the lymph nodes are affected.
Targeted (biological) therapies
This is a group of drugs that block the growth and spread of cancer. They target and interfere with processes in the cells that help cancer to grow.
The most widely-used targeted therapy is trastuzumab (Herceptin). Only people whose cancer has high levels of HER2 (called HER2 positive) will benefit from having trastuzumab. HER2 is a protein that helps cancer cells grow.
There are various tests to measure HER2 levels that are done on breast tissue removed during a biopsy or surgery.
Tubular breast cancer is likely to be HER2 negative. If your cancer is found to be HER2 negative, then trastuzumab will not help you.
Bisphosphonates are a group of drugs that can reduce the risk of breast cancer spreading in post-menopausal women. They can be used regardless of whether the menopause happened naturally or because of breast cancer treatment.
Bisphosphonates can also slow down or prevent bone damage. They’re often given to people who have, or are at risk of, osteoporosis (when bones lose their strength and become more likely to break).
Bisphosphonates can be given as a tablet or into a vein (intravenously).
Your specialist team can tell you if bisphosphonates would be suitable for you.
Being diagnosed with breast cancer can make you feel lonely and isolated.
Many people find it helps to talk to someone who has been through the same experience as them. Breast Cancer Care’s Someone Like Me service can put you in touch with someone who has had a diagnosis of breast cancer, so you can talk through your worries and share experiences over the phone or by email. You can also visit our confidential online Forum and join one of the ongoing discussions.
If you would like any further information and support about breast cancer or just want to talk things through, you can speak to one of our experts by calling our free Helpline on 0808 800 6000.
