What are the common types of cancer treatment?
Cancer treatment can involve various approaches, and the choice of treatment depends on the type and stage of cancer, as well as individual factors such as the patient's overall health. Common types of cancer treatment include:
Surgery:
Purpose: Surgical procedures aim to remove cancerous tumors and surrounding tissues. Surgery is often used for localised tumors and may be curative in some cases.
Methods: Different surgical techniques include traditional open surgery, minimally invasive surgery (laparoscopy or robotic surgery), and in some cases, reconstructive surgery.
Chemotherapy:
Purpose: Chemotherapy involves the use of drugs to kill or inhibit the growth of rapidly dividing cancer cells. It is a systemic treatment that can reach cancer cells throughout the body.
Administration: Chemotherapy can be given orally or intravenously (IV), and the treatment may involve a single drug or a combination of drugs.
Radiation therapy:
Purpose: Radiation therapy uses high doses of radiation to target and destroy cancer cells. It can be used to shrink tumors before surgery, eliminate remaining cancer cells after surgery, or as a primary treatment.
Methods: External beam radiation (external machine) and internal radiation (implanted radioactive material) are common methods.
Immunotherapy:
Purpose: Immunotherapy stimulates the body's immune system to recognise and attack cancer cells. It can enhance the immune response or block signals that cancer cells use to evade the immune system.
Types: Monoclonal antibodies, immune checkpoint inhibitors, adoptive cell therapy, and cancer vaccines are examples of immunotherapy approaches.
Targeted therapy:
Purpose: Targeted therapy drugs specifically target molecules involved in cancer cell growth and survival. These drugs can interfere with specific pathways that contribute to cancer development.
Examples: Tyrosine kinase inhibitors, hormone therapies, and angiogenesis inhibitors are common types of targeted therapies.
Hormone therapy:
Purpose: Hormone therapy is used for cancers that are hormone-sensitive, such as breast and prostate cancers. It aims to block or interfere with the hormones that fuel certain types of cancers.
Methods: Medications may be used to block hormone production or inhibit hormone receptors in cancer cells.
Precision medicine:
Purpose: Precision medicine involves tailoring treatment based on the genetic makeup of the patient's cancer. Molecular profiling helps identify specific genetic changes driving the cancer, allowing for targeted therapies.
Methods: Genomic testing and analysis guide the selection of targeted treatments.
These treatments can be used alone or in combination, depending on the specific characteristics of the cancer and the overall treatment plan. Additionally, supportive care, including pain management, nutritional support, and psychological support, is often integrated into cancer treatment plans to address the overall well-being of the patient. Treatment decisions are typically made through a collaborative effort involving oncologists, surgeons, radiation oncologists, and other healthcare professionals.
Why does cancer treatment affect my oral health?
Cancer treatments, particularly chemotherapy and radiation therapy to the head and neck region, can have positive effects on oral health. Here are some reasons why cancer treatment may impact oral health:
Chemotherapy:
Mucositis: Chemotherapy drugs can damage the rapidly dividing cells of the oral mucosa, leading to inflammation and sores. This condition is known as mucositis and can cause pain, difficulty swallowing, and an increased risk of infections.
Weakened immune system: Chemotherapy can suppress the immune system, making individuals more susceptible to infections, including oral infections.
Radiation therapy:
Xerostomia (dry mouth): Radiation therapy, especially when directed toward the head and neck, can damage the salivary glands, leading to reduced saliva production. Dry mouth, or xerostomia, increases the risk of tooth decay, gum disease, and oral infections.
Soft tissue damage: Radiation can cause damage to the soft tissues in the mouth, leading to inflammation, pain, and difficulty eating.
Osteoradionecrosis: Facial and jaw bones are often collaterally exposed to radiation during the treatment of head and neck cancers. The exposure results in decreased vitality of the bones making them less able to heal and more susceptible to infection following any trauma such as dental extractions
Suppressed immune system:
Both chemotherapy and radiation therapy can weaken the immune system, making it more challenging for the body to fight off infections, including those affecting the oral cavity.
Changes in blood counts:
Chemotherapy can affect the production of blood cells, including white blood cells, which play a crucial role in the body's defense against infections. A compromised immune system can contribute to oral health issues.
Nutritional challenges:
Cancer treatments may cause changes in taste, appetite, and the ability to eat certain foods. Poor nutrition can impact overall health, including oral health.
Increased susceptibility to infections:
The combination of weakened mucosal barriers, suppressed immune function, and changes in the oral environment can make individuals undergoing cancer treatment more susceptible to oral infections.
Medication side effects:
Some medications used in cancer treatment may have side effects that affect oral health. For example, certain drugs may cause gum bleeding, gum swellings, altered taste perception, or oral ulcers.
Effects on tooth development:
Cancer treatments administered during childhood can affect the development of teeth and the structure of the jaw, potentially leading to dental issues later in life.
It is important to note that the impact of cancer treatment on oral health can vary depending on the type of cancer, the specific treatment regimen, and individual factors. Dental care and oral hygiene become especially important during and after cancer treatment to manage potential side effects and prevent complications. Coordination between oncology and dental healthcare teams is crucial to providing comprehensive care and addressing oral health concerns in individuals undergoing cancer treatment.
Dental care before cancer treatment
Dental care before cancer treatment is crucial to minimise potential complications during and after cancer therapy. Here are important steps to consider for dental care before undergoing cancer treatment:
Pre-treatment dental evaluation:

Can dental X-rays detect mouth cancer?
Dental X-rays are an essential diagnostic tool that can help detect various oral conditions, including signs of jaw cancer. They provide detailed images of the teeth, jawbone, and surrounding tissues, allowing dentists and oral health professionals to spot abnormalities or suspicious lesions that may indicate cancer.
However, it is important to note that dental X-rays alone are not usually sufficient to conclusively diagnose jaw cancer. While they can show changes in bone density and reveal irregularities or lesions, a definitive diagnosis typically requires additional tests, such as a biopsy, to confirm the presence of cancerous cells.
Why might cancer patients need to have their teeth removed?
Cancer patients may need tooth extractions for several reasons, all influenced by their overall health, cancer treatment plan, and potential complications.
Certain chemotherapy drugs can weaken the immune system and increase the risk of infection. Additionally, radiation therapy, especially for cancers of the head and neck, can affect oral health. It can damage salivary glands, leading to dry mouth (xerostomia), and reduce blood supply to the jawbone, heightening the risk of osteoradionecrosis—a serious condition where the jawbone fails to heal properly after trauma, including dental procedures.
To minimise these risks, dental extractions may be recommended before initiating chemotherapy or radiation therapy. This preventive step is taken to remove teeth that are in poor condition and are likely to cause complications during or after cancer treatment.
It is important to note that the decision to remove teeth is made on a case-by-case basis, and the recommendation is typically a result of collaboration between the oncologist and dentist. Dental care is an integral part of cancer treatment planning, and addressing oral health issues before, during, and after cancer treatment is essential for the overall well-being of the patient.
Does radiation for breast cancer affect teeth?
Radiation therapy for breast cancer today is highly targeted and generally has minimal impact on the teeth due to its precise focus away from the oral area. However, certain medications commonly used in managing breast cancer can have effects on dental health.
For example, bisphosphonates, often prescribed for advanced breast cancer, can compromise bone healing. This becomes particularly relevant during invasive dental procedures, such as extractions, which can increase the risk of osteonecrosis of the jaw—a condition where the jawbone fails to heal properly after injury. The effects of bisphosphonates can be long-lasting, with the drug remaining in the bone for years after cessation of treatment.
Therefore, if you have a history of breast cancer treatment, it is important to inform your dentist before undergoing any dental treatments to ensure appropriate precautions are taken.
