What is Cancer Surgery?

Cancer surgery involves the removal of a tumor and surrounding tissues during an operation. It is often a primary method of treatment and can be used alone or in combination with other treatments such as chemotherapy and radiation therapy.

Why is Surgery Performed for Cancer?

Surgery can be performed for various reasons, including:

Diagnostic purposes: To obtain a tissue sample for biopsy to confirm the presence of cancer.
Staging: To determine the extent of the cancer.
Curative intent: To remove the entire tumor when it is localized.
Palliative care: To relieve symptoms and improve the quality of life in advanced stages of cancer.

Types of Cancer Surgeries

There are multiple types of surgeries used to treat cancer:

Curative surgery: Removes the entire tumor when confined to one area.
Preventive surgery: Removes tissue that does not yet contain cancer cells but has a high risk of developing cancer.
Diagnostic surgery: Includes biopsies to confirm the diagnosis.
Staging surgery: Determines the size of the tumor and the extent of its spread.
Debulking surgery: Removes as much of the tumor as possible when complete removal isn't feasible.
Palliative surgery: Alleviates symptoms caused by cancer to improve quality of life.

How is Surgery Planned?

Planning for surgery involves several steps:

Medical evaluation: Includes a comprehensive assessment of the patient’s overall health.
Imaging studies: Such as CT scans, MRIs, and X-rays to locate the tumor and understand its size and spread.
Preoperative tests: Blood tests and other diagnostics to ensure the patient is fit for surgery.
Consultation with a multidisciplinary team: Involves surgeons, oncologists, radiologists, and other specialists to formulate the best surgical plan.

Risks and Complications

While surgery is often beneficial, it does carry risks and potential complications, such as:

Infection
Bleeding
Reaction to anesthesia
Damage to nearby organs
Pain and discomfort
Delay in wound healing

Recovery and Postoperative Care

Recovery varies depending on the type and extent of surgery. Postoperative care typically includes:

Pain management
Wound care
Physical therapy to regain strength and mobility
Follow-up visits to monitor recovery and detect any recurrence
Adjuvant therapies like chemotherapy or radiation therapy if needed

Advancements in Surgical Techniques

Recent advancements have significantly improved the outcomes of cancer surgery:

Minimally invasive surgery: Includes laparoscopic and robotic-assisted surgeries which reduce recovery time and complications.
Image-guided surgery: Uses real-time imaging to increase precision.
Sentinel lymph node biopsy: Helps in accurate staging and reduces the need for extensive lymph node removal.

Conclusion

Cancer surgery is a critical component of cancer treatment, offering the possibility of curing localized cancers and improving the quality of life for those with advanced disease. With continuous advancements in technology and surgical techniques, the effectiveness and safety of cancer surgeries continue to improve.
