Oncology is a medical field focused on the diagnosis, treatment, and prevention of cancer. Different methods such as surgery, chemotherapy, radiotherapy, and biological therapy are used in cancer treatment, each with its own unique advantages and disadvantages.
| Treatment Method | Technological Advancements | Procedure | Benefits | Side Effects and Recovery Time |
|---|---|---|---|---|
| Surgery | Laparoscopy, robotic surgery, minimally invasive techniques | Surgical removal of the tumor | Complete removal of the tumor, curative in early-stage cancers | Bleeding, infection, wound healing issues. Recovery time varies based on the type of surgery and the patient’s overall condition. |
| Chemotherapy | Development of new drugs, targeted therapies | Administration of drugs that kill cancer cells via IV or orally | Kills cancer cells throughout the body, shrinks tumors | Hair loss, nausea, vomiting, bone marrow suppression. Recovery time varies based on the drug used and the patient’s overall condition. |
| Radiotherapy | High-energy radiation targeting tumors, IMRT (intensity-modulated radiotherapy) | Killing tumor cells with radiation beams | Tumor shrinkage, pain reduction | Skin redness, fatigue, nausea. Recovery time varies based on the radiation dose and treatment area. |
| Biological Therapy (Immunotherapy) | Monoclonal antibodies, CAR-T cell therapy | Enhancing the patient’s immune system to fight cancer cells | Targets cancer cells by activating the immune system, long-term response | Fever, fatigue, immune system attacking other cells (autoimmune reactions). Recovery time varies based on the drug used and the patient’s overall condition. |
