Our 24/7 cancer helpline provides information and answers for people dealing with cancer. We can connect you with trained cancer information specialists who will answer questions about a cancer diagnosis and provide guidance and a compassionate ear.
Our highly trained specialists are available 24/7 via phone and on weekdays can assist through video calls and online chat. We connect patients, caregivers, and family members with essential services and resources at every step of their cancer journey. Ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
If you can’t have major surgery because your lung function is at a low level or you have other serious medical problems, or if the cancer has spread too much to be removed, other treatments may be used to relieve some symptoms.
These treatments, called palliative procedures, can relieve symptoms, but they do not cure the cancer and are recommended only if you can’t have surgery to completely remove the tumor. If you are treated with these procedures you may also get radiation therapy.
If the tumor is blocking airways in the lung, it might lead to pneumonia or shortness of breath. Removing most of the tumor through a bronchoscope or destroying most of it with a laser (on the end of a bronchoscope) can be helpful. In some cases, a bronchoscope may be used to place a stent (a stiff tube) made of metal or silicone in the airway after treatment to help keep it open.
In rare instances, fluid can build up inside the chest (outside of the lungs), press on the lungs and affect breathing. Usually, a hollow needle is put through the skin and into the pleural space to remove the fluid. (This is known as a thoracentesis.) For most people, removing the fluid can relieve breathing problems right away, but the fluid will often build up again quickly if nothing else is done.
To remove the fluid and keep it from coming back, doctors sometimes do a procedure called pleurodesis. A small cut is made in the skin of the chest wall, and a hollow tube is placed into the chest to remove the fluid. Either talc or a drug such as doxycycline or certain chemotherapy drugs (like bleomycin) is then instilled into the chest cavity. This causes the linings of the lung (visceral pleura) and chest wall (parietal pleura) to stick together, sealing the space and limiting further fluid buildup. The tube is often left in for a day or two to drain any new fluid that might collect.
This is another way to control fluid buildup. One end of the catheter (a thin, flexible tube) is placed in the chest through a small cut in the skin, and the other end is left outside the body. This is done in a doctor’s office or hospital. Once in place, the catheter can be attached to a special bottle or other device to allow the fluid to drain out on a regular basis.
If the cancer spreads to the liver, treating the liver tumors may help with symptoms. When there are only 1 or 2 tumors in the liver, they may be removed with surgery. If there are more than just a few liver tumors (or if a person is too sick for surgery), other techniques may be used.
Ablation techniques destroy tumors without removing them. They are generally not used for large tumors, and are best for tumors no more than about 2 cm (a little less than an inch) across.
Arterial embolization (also known as transarterial embolization or TAE): This is another option for tumors that can’t be removed completely. It can be used for larger tumors (up to about 5 cm or 2 inches across). This technique reduces the blood flow to the cancer cells by blocking the branch of the hepatic artery feeding the area of the liver containing the tumor. Blood flow is blocked (or reduced) by injecting materials that plug up the artery. Most of the healthy liver cells will not be affected because they get their blood supply from the portal vein.
In this procedure a catheter is put into an artery in the inner thigh and threaded up into the liver. A dye is then injected into the bloodstream to allow the doctor to monitor the path of the catheter via angiography, a special type of x-ray. Once the catheter is in place, small particles called microspheres are injected into the artery to plug it up.
Radioembolization: In the United States, this is done by injecting small radioactive beads into the hepatic artery. The beads travel to the tumor and give off small amounts of radiation only at the tumor sites.
Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing.
