Summary
Surgery removes tumours and provides tissue for diagnosis and staging, and can be curative, combined with other treatments, or used to relieve symptoms depending on the cancer's extent.
Key takeaways
- Surgery can remove tumours entirely in early-stage, localised cancers.
- Minimally invasive approaches often allow faster recovery than open surgery.
- Pathology results from removed tissue guide decisions about further treatment.
- Surgery can also relieve symptoms in advanced cancer, even without curative intent.
- Pre-surgical assessment ensures patients can safely tolerate the procedure.
What it is
Cancer surgery involves physically removing a tumour and, when needed, surrounding tissue or nearby lymph nodes to check for spread. Techniques range from open surgery to minimally invasive laparoscopic or robotic approaches, chosen based on tumour location, size, and the patient's overall health.
What it means for you
Knowing whether your surgery aims to cure, stage, or relieve symptoms helps you understand what to expect afterwards, including whether further treatment may be recommended based on findings. Discussing recovery expectations beforehand helps with planning.
Testing
Preoperative imaging and biopsy confirm tumour location and extent, while blood work and organ function tests assess surgical fitness. After surgery, pathology examination of the removed tissue confirms stage, margins, and any biomarkers relevant to further treatment.
Associated cancer types
Surgery is used across most solid tumours, including breast, colorectal, lung, prostate, kidney, and skin cancers, as well as to remove metastases in select cases or to place devices for other treatments such as chemotherapy ports.
Treatment options
Approaches range from minimally invasive laparoscopic or robotic surgery to open procedures, chosen based on tumour characteristics. Surgery may be combined with neoadjuvant treatment beforehand or adjuvant chemotherapy or radiation afterwards depending on pathology results.
Questions patients ask
- What type of surgery is recommended and why?
- What are the risks and expected recovery time for this procedure?
- Will lymph nodes be removed, and what does that mean for me?
- What will the pathology report tell us and when will results be available?
- Will I need chemotherapy or radiation after surgery?
Frequently asked questions
How long is recovery after cancer surgery?
Recovery time varies widely by procedure, from days for minimally invasive surgery to several weeks for more extensive operations.
Will I need other treatments after surgery?
This depends on pathology results after surgery; some patients need additional chemotherapy or radiation, while others may not.
What is a margin and why does it matter?
A margin is the rim of tissue removed around a tumour; clear margins (no cancer cells at the edge) generally indicate a lower chance of local recurrence.
