Cancer Treatment Options: Medications, Surgery & More

Understanding Cancer Treatment Options

A cancer diagnosis brings a wave of uncertainty, and understanding the available treatment options is a crucial first step toward navigating the journey ahead. Cancer treatments aim to stop, slow, or eliminate cancer cells, and often involve a combination of approaches tailored to the specific type of cancer, its stage, and the individual’s overall health. While surgery, chemotherapy, and radiation therapy are the cornerstones of cancer care, advancements in immunotherapy, targeted therapy, and ablation techniques are continually expanding the possibilities for effective treatment.

How Cancer Treatment Works

Oncologists, doctors specializing in cancer treatment, have a wide array of medications and procedures at their disposal. These are designed to destroy cancer cells, prevent their growth, or deprive them of the resources they need to survive. Sometimes, treatments target specific parts of the cancer cell, while others work by boosting the body’s own immune system to recognize and attack the cancer. A cancer care team often considers clinical trials, which offer access to cutting-edge therapies, as part of a patient’s treatment plan. The Jonah Center at ECMC Hospital in Buffalo, NY, for example, actively participates in clinical trials.

Medication-Based Therapies

Several types of medications are commonly used in cancer treatment:

Chemotherapy: This involves using drugs – administered through infusions, injections, creams, or oral medications – to kill rapidly dividing cells, including cancer cells. However, chemotherapy can also affect healthy cells, leading to side effects like anemia, hair loss, nausea, and vomiting.
Immunotherapy: This approach harnesses the power of the immune system to fight cancer. Cancer cells often have ways of hiding from the immune system, but immunotherapy helps the body recognize and destroy these cells.
Targeted Therapy: Some cancer cells contain specific genetic mutations that drive their growth. Targeted therapy drugs are designed to block or disable these abnormal proteins, effectively halting cancer progression.
Hormone Therapy: Certain cancers, particularly breast and prostate cancers, rely on hormones to grow. Hormone therapy aims to slow or stop the growth of these cancers by blocking hormone production or action.

Oncologists may adjust medication regimens based on a patient’s response and tolerance, switching within the same drug class to manage side effects or overcome resistance.

Surgical Interventions

Surgery remains a vital component of cancer treatment, often used to remove tumors or cancerous tissue. Surgeons may perform open surgery, involving a large incision, or minimally invasive surgery, utilizing small incisions and specialized tools like laparoscopes or robotic arms. The Buffalo Medical Group emphasizes tailoring cancer treatments to each individual, including surgical options.

Sometimes, complete removal of a tumor isn’t possible, and surgeons may remove part of it to alleviate symptoms or improve quality of life.

Ablation Techniques: Destroying Cancer with Temperature

Ablation therapy uses extreme temperatures to destroy cancer cells. This can be particularly useful for shrinking tumors and relieving symptoms. Common ablation techniques include:

Cryosurgery/Cryotherapy: This method uses extreme cold, typically liquid nitrogen or argon gas, to freeze and destroy abnormal tissue. It’s often used for skin cancer, some eye cancers, and cervical cancer.
Hyperthermia: While not yet widely available, hyperthermia involves exposing cancerous tissue to high temperatures to kill cancer cells or enhance the effectiveness of other treatments. Radiofrequency ablation is a type of hyperthermia that uses high-energy radio waves to generate heat.
Laser Surgery: This technique uses focused light beams to precisely cut and destroy cancerous tissue. It’s often used for skin cancers and cancers of the cervix, esophagus, vagina, and lungs.

Side effects of ablation therapy can vary depending on the location of the cancer and may include pain, discomfort, bleeding, or damage to nearby healthy tissue.

Radiation Therapy: Targeting Cancer with Energy

Radiation therapy uses high-energy radiation to damage the DNA of cancer cells, preventing them from growing and dividing. A radiation oncologist may recommend radiation therapy as the sole treatment or in combination with other therapies, such as surgery. Kaleida Health highlights radiation therapy as one of the three main treatments for cancer, alongside surgery and chemotherapy.

There are two main types of radiation therapy:

External Beam Radiation Therapy: This is the most common type, where a machine directs a beam of high-energy radiation at the tumor.
Internal Radiation Therapy: This involves placing a radioactive source inside the body, often used for cancers of the head, neck, cervix, breast, uterus, or prostate.

Side effects of radiation therapy are usually mild and localized to the treated area, potentially including fatigue, diarrhea, or skin irritation.

Bone Marrow Transplants: Rebuilding the Blood System

Also known as hematopoietic stem cell transplants, these procedures involve replacing damaged or cancerous bone marrow with healthy stem cells. This can be used to treat blood cancers that haven’t responded to other treatments or have returned after remission. Bone marrow transplants can also be used to restore healthy blood cells after high-dose chemotherapy.

There are two types of bone marrow transplants:

Allogeneic: Uses healthy stem cells from a donor.
Autologous: Uses the patient’s own stem cells.

Side effects can include a weakened immune system and, in the case of allogeneic transplants, the risk of graft-versus-host disease (GVHD), where the transplanted cells attack the patient’s tissues.

Navigating Cancer Care: A Collaborative Approach

Effective cancer care requires a collaborative approach involving surgeons, oncologists, and other specialists. Many cancer centers, like those in Buffalo, NY, emphasize multidisciplinary teams that discuss each case to develop a comprehensive and individualized treatment plan. It’s critical to remember that cancer treatment is not a one-size-fits-all process, and the best approach will vary depending on the individual and the specifics of their cancer. If you or a loved one has been diagnosed with cancer, discussing all available treatment options with a qualified healthcare professional is essential.
