Breast cancer is a topic that touches the lives of millions of people around the world. It is a disease that not only affects the individual diagnosed but also has a significant impact on their families, friends, and communities.

In this comprehensive guide, we will delve into breast cancer, exploring its treatment options, the path to recovery, and the vital role of support.

Breast Cancer Treatment

Cancer treatment refers to a range of medical interventions aimed at combating and managing the growth and spread of cancer cells within the body. The objective is to eliminate cancerous cells, prevent their recurrence, alleviate symptoms, and improve patients’ overall quality of life.

Various factors are considered when determining an appropriate course of treatment, such as:

The type and subtype of the tumour including hormone receptor status.

• The stage of cancer.
• Results of genomic tests (DNA testing)
• Patient’s overall health
• Patient’s personal preferences

Based on these, the breast cancer care team specifically tailors the treatment as per individual patient’s needs. However, a few general methods are followed for treating early-stage and locally advanced breast cancer.

Surgery

Surgery is one of the commonly used treatment options used for treating breast cancer at an early stage. It involves removing the tumour or the entire breast. Two types of surgery are generally performed to treat breast cancer:

This intricate procedure involves the skilled hands of a surgical oncologist who carefully plans and executes the operation while considering factors such as tumour location, size, and stage. With advancements in medical technology, minimally invasive surgical techniques, including laparoscopy and robotic-assisted surgery, have gained popularity due to the shorter recovery time and reduced pain compared to traditional open surgeries.

Radiation Therapy

Radiation therapy, or radiotherapy, is a powerful cancer treatment that uses high-energy radiation to destroy cancer cells. It damages the DNA in these cells, preventing them from multiplying and spreading. There are two ways to administer this treatment: externally, using a machine that directs the radiation to the affected area, or internally, by placing radioactive material near the tumour inside the body. Radiation therapy is an important part of cancer treatment and can be used to shrink tumours before surgery, kill any remaining cancer cells after surgery, or provide relief for patients with advanced-stage cancer. It requires careful planning and precise delivery to ensure it is effective and minimises damage to healthy tissues. Radiation therapy is often the preferred mode of treatment for invasive cancer, especially in young patients, patients with large tumours and patients with hormone receptor-negative tumours. Radiation therapy is also commonly used for Ductal carcinoma in situ (presence of cancerous cells inside the milk ducts in the breast) patients.

Chemotherapy

Chemotherapy is a common and effective cancer treatment. Drugs are used to kill fast-dividing cells, including cancer cells. The drugs can be given orally, by injection, or intravenously to stop tumour growth and prevent spreading. Specific drugs are chosen based on the cancer type and patient factors. However, chemotherapy also affects healthy cells that divide rapidly, causing side effects like hair loss and digestive issues.

Side effects may include hair loss, fatigue, nausea, and decreased cell counts. However, advancements in research have led to targeted therapies and reduced doses that minimise side effects while maximising effectiveness. Chemotherapy is continually being improved and personalised to achieve better outcomes for cancer patients.

Hormone Therapy

Hormone therapy is an important part of cancer treatment, especially for tumours that test positive for oestrogen (ER-positive) or progesterone receptors (PR-positive). Such kinds of tumours use hormones to fuel their growth. Hormone therapy works by blocking or reducing these hormones.

Hormonal therapy is used independently or sometimes after chemotherapy to obtain the best results. Hormone therapy is sometimes used before surgery to shrink a tumour. This aids in the surgery and also lowers the risk of recurrence. In some cases, usually, hormone therapy is given 3 to 6 months before surgery and sometimes continued even after the surgery. This is known as neoadjuvant hormone therapy. When hormone therapy is administered solely after surgery to reduce the risk of recurrence, it is called adjuvant hormone therapy.

Targeted Therapy

Targeted therapy is a novel approach in cancer treatment that attacks specific genes, proteins and tissues involved in the growth and survival of cancer cells. Unlike traditional chemotherapy, which often affects healthy cells alongside cancerous ones, targeted therapy specifically tailors treatment to the characteristics of individual tumours.

This highly specialised approach utilises drugs that interfere with specific proteins or pathways involved in tumour formation and proliferation. The development of targeted therapies has transformed the landscape of cancer care, allowing for more effective treatments with fewer side effects.

Immunotherapy

Immunotherapy is a new branch of cancer treatment that harnesses the immune system to fight against cancer. It has shown promise in treating various types of cancers and involves using substances like antibodies to target cancer cells. This treatment offers the possibility of lasting remission and better survival rates with fewer side effects compared to chemotherapy or radiation therapy. Although this field is still evolving, immunotherapy has the potential to revolutionise cancer treatment worldwide.

Treatment of Breast Cancer Based on Stage

It is a known fact that the stage plays an important role in prognosis and recovery. Well, in treatment too. The stage is one of the primary factors which guides therapy choices.

Staging ranges from 0 to IV, reflecting the size of the tumour, involvement of the lymph node, and the level of spreading to other organs. Here’s a brief and generic overview of how treatment choice varies based on stage:

Stage 0 (Ductal Carcinoma In Situ – DCIS):

Cancer cells are only present in the ducts and nodules of the breast and have not spread to the surrounding tissues. This is also known as non-invasive cancer. Treatment often involves surgery, specifically a lumpectomy or mastectomy. Radiation therapy may follow surgery in some cases. Hormone therapy may be recommended for hormone receptor-positive DCIS.

Stage I:

This is when the disease is invasive. 2 types of cancer cells are found during this stage – the tumour size is up to 2 centimetres (cm) and has not spread to the lymph nodes (Stage IA) and where the tumour size is less than 2 cm or the tumour is in the lymph nodes of the breast and not in the breast tissue (Stage IB). The common treatment for Stage I involves surgery, such as lumpectomy or mastectomy. Radiation therapy may be recommended following surgery, especially after a lumpectomy. Chemotherapy is usually not required for Stage I unless other high-risk factors are present.

Stage II:

This is also an invasive breast cancer which can be of two types:

• Stage IIA: Where either there’s no tumour in the breast but cancer cells have spread to 1 to 3 lymph nodes or the tumour is 2 to 5 cm in size and may or may not have spread to lymph nodes.
• Stage IIB: In this stage, the tumour is 2 to 5 cm in size and has spread to 1 to 3 axillary lymph nodes or the tumour is larger than 5cm and has not spread to axillary lymph nodes.

Treatment for Stage II may involve surgery (lumpectomy or mastectomy). Radiation therapy is also often recommended, particularly if the tumour is large or lymph nodes are involved. Chemotherapy may be considered, especially for larger tumours or lymph node involvement.

Stage III:

Stage III cancer, which is also invasive, can be of three types:

• Stage IIIA: The tumour can be of any size or there’s no tumour at all. The disease has spread to 4 lymph nodes in the breast but has not spread to other parts of the body.
• Stage IIIB: The disease has spread up to 9 lymph nodes. The tumour can be of any size or there are no tumours at all.
• Stage IIIC: There may be no sign of cancer in the breast or the tumour can be of any size or may have spread to the chest wall or breast skin. The disease has spread to 10 or more axillary lymph nodes or the nodes above or below the breastbone or collarbone.

Treatment for Stage III usually begins with surgery (mastectomy) and may involve removing lymph nodes. Chemotherapy is typically given before surgery (neoadjuvant chemotherapy) to shrink tumours. Radiation therapy is used after surgery if needed.

Stage IV (Metastatic Breast Cancer):

This is the most advanced stage of breast cancer where the tumour can be of any size, but the disease has spread to other organs and tissues such as distant lymph nodes, bones, lungs, brain or chest wall. Treatment focuses on controlling the cancer and relieving symptoms rather than cure. Options include chemotherapy, targeted therapy, hormone therapy, and immunotherapy. Radiation therapy may be used for symptom relief or to target specific metastatic sites.

The Road to Recovery

Receiving a breast cancer diagnosis can be overwhelming and the journey to recovery can be physically and emotionally challenging. However, with the right support and resources, many individuals successfully navigate this path.

Faith over Fear

Breast cancer is a formidable adversary, but advances in research and treatment have improved the outlook for those affected. A breast cancer diagnosis is not the end of the road; it is the beginning of a journey filled with challenges and triumphs. With the right medical care, support network, and personal determination, many individuals successfully navigate this path, emerging as survivors who inspire others.

Remember that you are not alone on this journey. Reach out for support, advocate for your needs, and prioritise your physical and emotional well-being. Together, we can raise awareness, promote early detection, and support those affected by breast cancer, ensuring that more individuals continue to celebrate life beyond this diagnosis.
