cancer cells develop in a primary site such as the breast, colon
or lung. Cells from these cancers can spread or metastasize
to other parts of the body where they may form new tumors.
two basic strategies to treat cancer. These include local and
systemic. Systemic treatment, chemotherapy, is typically
a drug injected into the bloodstream and is carried throughout
the body. Local treatments such
as surgery, radiation therapy, Selective Internal Radiation or
chemoembolization (see in other section of web site), and now
radiofrequency ablation attack cancer at a specific site.
ablation (RFA) is a procedure used to treat a variety of inoperable
tumors in a minimally invasive way. RFA uses energy delivered
through a metal probe inserted into a tumor under radiographic
guidance. RF energy causes atoms in the cells to vibrate and
create friction. This generates heat leading to death of
tumor cells. The heat generated in tissues treated with
RF energy causes permanent damage and destruction of tumor cells.
is safe, effective treatment option approved by the Food and
Drug Administration (FDA) for liver and soft tissue. RFA studies
have shown significant benefit for lesions in various locations
including liver (primary and secondary) breast (combined with
surgery to treat early stage cancers), kidney, lung (predominantly
stage I and stage II disease), bone, adrenal and soft tissue.
Most importantly, RFA can be an effective treatment for patients
whose cancers cannot be treated surgically.
can be used before during and after surgery, radiation therapy,
or in addition systemic treatments. Countless patients with a
variety of medical problems have been treated with this technique.
patient is asleep RFA probe is placed in the lesion through
the skin under image guidance. The lesion is heated using
a generator attached to the probe and the lesion is destroyed
