Breast cancer treatment without surgery typically depends on several factors. These factors includes the stage of the cancer, its severity, and the patient’s overall health. While surgery is often the primary treatment for breast cancer, there are alternative approaches for certain cases. Some non-surgical treatments commonly used for breast cancer include chemotherapy, radiation therapy, immunotherapy, hormonal therapy and cryoablation. In this article, we will discuss everything about breast cancer treatment without surgery.
What are the non-surgical treatment options for breast cancer?
Breast cancer treatment without surgery primarily uses chemotherapy. In chemotherapy, we use drugs to kill or inhibit the growth of cancer cells. During the pre-surgery period, doctors frequently employ neoadjuvant chemotherapy to shrink tumors, making their removal easier. After the surgery, we employ adjuvant chemotherapy to kill any remaining cancer cells. In radiation therapy, we use high-energy beams to kill cancer cells. After surgery, you can kill cancer cells in the breast, chest wall, or lymph nodes with it. During preparation for breast cancer surgery, this treatment actively shrinks tumors.
Hormone-receptive breast cancer cells rely on hormones like oestrogen and progesterone for growth. Hormone-receptive breast cancer patients undergo treatment with hormone therapy. Hormone treatment is yet another breast cancer treatment without surgery. It functions by either inhibiting the actions of these hormones or lowering the body’s production of them. Targeted therapy drugs specifically target cancer cells by interfering with specific molecules involved in cancer growth and progression. Immunotherapy drugs help the body’s immune system recognise and attack cancer cells. It is less commonly used in breast cancer as in some other types of cancer.
Immunotherapy is being studied and may become a more significant part of treatment in the future. Cryotherapy involves freezing cancer cells to destroy them. In certain cases of small tumors in the breast, doctors perform cryoablation as an alternative to more commonly used treatments.
What are the types of breast cancer surgeries?
Different types of surgeries are used to treat breast cancer based on the stage, size, location, and other factors. Some commonly used breast cancer surgery types are discussed as follows:
- A lumpectomy (breast-conserving surgery) procedure involves removing the tumour. It also removes a small margin of surrounding healthy tissue while preserving the rest of the breast. After a lumpectomy, radiation therapy is typically used to reduce the risk of cancer recurrence.
- A mastectomy involves removing the entire breast tissue. There are several types of mastectomy. The chest wall muscles underneath the breast are preserved while this method involves removing the entire breast tissue.
- A modified radical mastectomy, involves the removal of the entire breast tissue and some axillary lymph nodes. In a less common type of mastectomy for the extensive spread of cancer, the chest wall muscles are typically utilized.
- Skin-sparing mastectomy involves the removal of breast tissue while preserving most of the skin over the breast. This allows for immediate breast reconstruction.
- Nipple-sparing mastectomy involves the removal of breast tissue while preserving the nipple and areola. We perform an immediate breast reconstruction together.
- A sentinel lymph node biopsy is a procedure that involves removing one or a few sentinel lymph nodes. Sentinel lymph node is the first lymph nodes to which cancer cells are likely to spread. If they are negative for cancer, it may indicate that cancer has not spread to other lymph nodes.
- Axillary lymph node dissection used in cases where cancer has spread to the sentinel lymph nodes. If risk of spreading is high, more extensive lymph node removal may be necessary. Axillary lymph node dissection involves removing a greater number of lymph nodes from the armpit area.
- Reconstructive surgery following breast removal, some women choose to undergo breast reconstruction to restore the shape and appearance of the breast. It uses similar tissue from other parts of the body.
How does hormone therapy work on breast cancer?
Hormonal treatment functions by either inhibiting the actions of these hormones or lowering the body’s production of them. Hormone receptor-positive breast cancers commonly use oestrogen-blocking medications. Such breast cancer relies on oestrogen to grow. These medications block the effects of oestrogen or reduce its production in the body. They are responsible for slowing or stopping the growth of hormone-sensitive breast cancer cells. Patients with breast cancer often undergo adjuvant therapy with oestrogen-blocking medications after surgery to reduce the risk of cancer recurrence. In advanced or metastatic cases, doctors may use these medications as palliative therapy. Hormone therapy can be used alone or in combination with other treatments methods. The choice of combination depends on the stage and characteristics of the breast cancer. Various other factors, such as the stage of the cancer, menopausal status, and individual patient preferences, influence the choice of medication and treatment duration.
What are the common hormone-blocking medicines for cancer?
Hormone therapy is a common treatment for breast cancer that is hormone receptor-positive. Hormone receptor-positive breast cancers have receptors for the hormones oestrogen and/or progesterone, which promote their growth. Here are some common hormone-blocking medicine for breast cancer:
Selective Estrogen receptor modulators (SERMs) is an oestrogen-blocking medication for breast cancer. It blocks the oestrogen receptors in breast cancer cells, preventing oestrogen from binding to them and enhancing their growth. Premenopausal and postmenopausal women with hormone receptor-positive breast cancer are ideal candidate. SERMs also reduce the risk of developing breast cancer in high-risk women.
Aromatase inhibitors work by blocking the enzyme aromatase, which is responsible for converting other hormones into oestrogen in postmenopausal women. By reducing oestrogen levels in the body, aromatase inhibitors help to slow or stop the growth of hormone receptor-positive breast cancer cells.
Selective Oestrogen Receptor Degraders (SERDs) is another oestrogen-blocking medication for breast cancer which works by binding to the oestrogen receptors on breast cancer cells. It also promotes the degradation of oestrogen receptors, leading to a decrease in their number. Commonly employed in postmenopausal women with advanced or metastatic breast cancer.
Luteinizing Hormone-Releasing Hormone (LHRH) agonists work by reducing the production of oestrogen in premenopausal women. They suppress the production of hormones from the ovaries, leading to a temporary menopause-like state. In premenopausal women with hormone receptor-positive breast cancer, we often use LHRH agonists in combination with other hormone therapies or chemotherapy for treatment.
The choice of surgery depends on various factors, including the size and location of the tumour, the stage of the cancer, the woman’s preferences, and her overall health. It’s important for individuals to discuss their options thoroughly with their healthcare team to determine the most suitable treatment plan for their specific situation. You should discuss with your healthcare team which treatment options are most appropriate for your specific situation. To achieve the best outcomes, we can combine these treatments occasionally. Additionally, ongoing advances in breast cancer research may lead to new and more effective treatment options in the future.
