Screening for early detection of primary liver cancer is not performed routinely, but it may be considered for people at high risk for the disease. However, studies haven't determined if screening is beneficial for anyone. To diagnose liver cancer, a doctor must rule out other causes of liver dysfunction.
This complementary and alternative medicine (CAM) information summary provides an overview of the use of aromatherapy and essential oils primarily to improve the quality of life of cancer patients. This summary includes a brief history of aromatherapy, a review of laboratory studies and clinical trials, and possible adverse effects associated with aromatherapy use.
This summary contains the following key information:
Aromatherapy is the therapeutic use of essential oils (also known as volatile...
Blood tests that measure tumor markers -- the levels of these substances rise in the blood if someone has a particular cancer -- can aid diagnosis. Liver cancers secrete a substance called alpha fetoprotein (AFP) that is normally present in fetuses but goes away at birth. An elevated AFP in adults may indicate liver cancer as it is produced in 70% of liver cancers. Elevated levels of iron may also be a tumor marker.
Imaging with ultrasound is the initial diagnostic test as it can detect tumors as small as one centimeter. High resolution CT scans and contrast MRI scans are used to diagnose and stage these tumors.
Laparoscopy, using tools and cameras through small incisions, is useful for detecting small tumors, determining the extent of cirrhosis, or obtaining a biopsy, and confirm previous tests, among other things.
What Are the Treatments for Liver Cancer?
Any liver cancer is difficult to cure. Primary liver cancer is rarely detectable early, when it is most treatable. Secondary or metastatic liver cancer is hard to treat because it has already spread. The liver's complex network of blood vessels and bile ducts makes surgery difficult. Most treatment concentrates on making patients feel better and perhaps live longer.
Patients with early-stage tumors that can be removed surgically have the best chance of long-term survival. Unfortunately, most liver cancers are inoperable at the time it's diagnosed, either because the cancer is too advanced or the liver is too diseased to permit surgery. In some patients, chemotherapy is given directly into the liver (chemoembolization) to reduce tumors to a size that may make surgery possible. This may also be done without chemotherapy (bland emoblization) in some cases, using ethanol instead. After surgery, radiation and chemotherapy have shown no advantage in improving survival. Patients in remission must be monitored closely for potential recurrence.
