Surgery, the oldest form of treatment for cancer, is the initial procedure in the diagnosis and/or treatment of many solid cancers. There are many cancers where the role of surgery is limited to a
for diagnosis, since other therapies (chemo-
radiation therapy) are more effective and less debilitating.
Two major developments have greatly increased the use and success of surgery. First was the introduction of anesthesia in 1846. Second was the adoption of antiseptic principles in 1867. Freeing surgery from pain and infection enabled its extensive use in the treatment of tumors.
Surgery and other invasive procedures work by removing cancerous tissues. The goal is to remove or reduce the total body tumor burden. When surgery is used to make a cancer diagnosis, the surgeon removes a tissue sample and sends it to a laboratory for examination and identification.
When determining if surgery is an option for you, your doctor will consider the location, type, and size of the tumor. In addition, how aggressively the tumor is capable of growing and whether or not it has already metastasized is considered. Finally, your doctor will assess your general health and how to best preserve your quality of life.
Surgery is used in cancer treatment for many different reasons, from curing your disease to easing your pain.
This procedure involves removing body tissue that is not cancerous, but is likely to become cancerous. An example is using
(using the extreme cold temperatures) to destroy and remove precancerous cells on the cervix.
In diagnostic surgery, a tissue sample is removed and used to identify a specific cancer and make a diagnosis. The removed tissue is examined under a microscope to confirm the diagnosis and determine various features of the cancer that can be used to predict prognosis.
Staging surgery is used to determine the extent of the cancer in the body. While the physical exam, laboratory tests, and imaging studies are also used to stage a cancer, surgical staging often allows a more accurate assessment of how far the cancer has spread.
Attempting to remove the entire tumor when it appears to be in one area is known as curative surgery. It is thought of as a primary treatment for cancer, but it may be used with
When it is not possible to safely remove the entire tumor, debulking surgery is often done. In so doing, the surgeon attempts to remove as much of the tumor as possible, which can make the tumor more susceptible to
Palliative surgery is not intended to cure cancer. It is used to manage pain and treat complications of advanced cancer, such as a life-threatening obstruction or bleeding.
Supportive surgery is used to support other types of treatment. For example, surgery can be used to place a catheter into a vein, which then allows for the administration of
This procedure is used to restore your appearance after primary surgery. It can also be used to restore the function of an organ or body part. An example of this type of procedure is breast reconstruction after
In a biopsy, your doctor removes a sample of tissue for diagnostic tests. It is not possible to make the diagnosis of cancer without a tissue biopsy. There are a variety of biopsy procedures, some require surgery and are performed by surgeons. Others are done in the doctor's office with little anesthesia. Usually, a biopsy removes just a sample of the affected tissue. Occasionally, the entire tumor is removed during the biopsy. Regardless of how much tissue is removed, it must be examined in a laboratory for an accurate diagnosis.
The following are some of the more common tissue biopsy procedures.
In an incisional biopsy, your surgeon cuts through your skin to remove a small part of a larger tumor. This is usually done with local or regional anesthesia, which is numbing medication used in the area of the biopsy. General anesthesia, which puts you to sleep, may be needed if your tumor is in the chest or abdomen.
In an excisional biopsy, your surgeon cuts through your skin to remove the entire tumor. This is usually done with local or regional anesthesia. General anesthesia may be needed if your tumor is in the chest or abdomen.
fine needle biopsy, your doctor removes tissue or fluid samples through a very thin needle. Imaging techniques like
can be used to help guide the needle to the tumor. The procedure does not require hospitalization and can be done with local anesthesia. An advantage to this procedure is that it does not require a large incision through the skin. However in some cases, the needle cannot remove enough tissue for a definitive diagnosis.
A needle core biopsy is much like a fine needle biopsy, but the needle is slightly larger. This allows for removal of a larger sample of tissue.
During endoscopy, the doctor uses a flexible tube with a video camera or a viewing lens and a fiberoptic light source on the end to view areas in the body. Using this procedure, your doctor can see the tumor directly and get an idea of its size and location. In addition, a biopsy can be taken through the scope for diagnostic purposes. The procedure usually does not require an open surgical incision or general anesthesia. However, you will be given medication that will make you sleepy and more relaxed before the procedure.
An endoscope can be passed through natural body openings and into the following areas:
is done to view and possibly perform surgery on the organs in your abdomen, such as the intestines, stomach, gallbladder, and pelvic organs. Your surgeon inserts a laparoscope (a long, thin tube with a fiberoptic light source and video camera) into your abdomen, which allows viewing of abdominal organs.
Several small (half-inch) incisions are made just above or below the navel and carbon dioxide gas is injected through the incision to inflate the abdomen. This creates a larger space for your doctor to work. The laparoscope is inserted through one of the incisions and the camera transmits images of your organs on a video monitor. Your doctor may make additional small incisions in which other instruments can be inserted to move the organs around for better viewing and to perform any procedures, such as a tissue biopsy.
Because the incisions are very small, there is less pain associated with the procedure and recovery is faster than an open abdominal surgery. Laparoscopy may be performed under a local or general anesthetic and is usually done at a hospital.
A similar procedure involving the chest is called a thoracoscopy or mediastinoscopy.
Electrosurgery uses high-frequency electrical current applied by needles, blades, or electrodes to eliminate cancer cells. This procedure can be done in a doctor's office and with a local anesthesia. It is used for some cancers of the skin, oral cavity, anus, and rectum.
In cryosurgery, your doctor uses extremely cold temperatures to freeze and kill abnormal cells. Carbon dioxide, Freon, and nitrous oxide are the most common gaseous freezing agents. Or, your doctor can use a very cold probe, called a cryoprobe. This procedure can be done in a doctor's office and may involve local anesthesia. Cryosurgery is used to treat surface lesions, like
and precancerous and cancerous gynecologic conditions. Newer innovations have enabled this technique to treat areas deep within the body, like metastatic
prostate cancer. The use of cryosurgery for the definitive or curative management of prostate cancer is investigational.
Laser surgery uses a powerful beam of light energy to kill and remove cancerous tissue. Because the beam is so highly focused, it can be used for precise surgical work, like repairing the retina of an eye. Lasers are used to remove tumors in difficult-to-access areas or to minimize blood loss in highly vascular (containing many blood vessels) tissue. Laser surgery is also called photocoagulation or photoablation.
In photocoagulation, tissues are super-heated, which immediately destroys the tissue. This process is used to prevent blood loss when surgery is performed in an area with numerous blood vessels.
Photoablation occurs at temperatures at which tissue water boils. This results in a vaporization of the tissue. This procedure is used for incision and removal of diseased tissue.
Laser surgery can be done in the doctor's office with a local anesthesia. Sometimes performed in a hospital setting, this procedure is used for cancers of the
larynx, liver, rectum, and skin.
Mohs surgery, a procedure used with skin cancer, is a microscopically controlled surgery. After you are given local anesthesia, a specially trained surgeon shaves off the suspect tissue, layer by layer. After removal, each layer is examined under a microscope. The procedure ends when the excised tissue looks normal.
Chemosurgery is the combined use of layer-by-layer surgical resection of tissue and topical application of chemical agents.
When a less invasive procedure cannot provide adequate treatment, your surgeon may opt for open surgery. Open surgery always takes place in a hospital and with anesthesia (either general or local depending on the situation). In open surgery, an incision is made to remove part or all of the cancerous tissue.
Advances in surgical techniques, anesthesia, and the management of postoperative infections have greatly reduced the danger associated with surgery. However, there are some risks involved.
Possible complications during surgery can be due to the surgery itself, the anesthesia, or an underlying disease. Usually, the more complicated the surgery, the greater the risk.
Complications can include any of the following:
The following adverse effects may occur after surgery, but are usually not life threatening:
The following adverse effects are less common, but can be more serious:
There are some side effects and complications that are specific to the type and location of cancer. For example, a man with prostate cancer may have a radical
(removal of the prostate), which can cause
