Some people develop post-traumatic stress disorder (also known as PTSD) after experiencing a shocking, frightening or dangerous event. In English, this disorder is often referred to as PTSD for short.

Anyone can have PTSD at any age. This includes war veterans as well as people who have experienced or witnessed a physical or sexual assault, abuse, an accident, a catastrophe, a terrorist attack, or other serious events. People with this disorder may feel stressed or frightened, even when they are no longer in danger.

Not everyone with PTSD has experienced a dangerous event. In some cases, just knowing that a family member or close friend experienced a traumatic event can trigger PTSD.

Post-traumatic stress symptoms usually begin within three months of the traumatic incident, but sometimes emerge later. To meet the criteria for post-traumatic stress disorder, symptoms must last for more than one month and must be severe enough to interfere with aspects of daily life, such as personal or work relationships. Symptoms also must not be related to medications, substance use, or other illnesses.

Treatment may have ended long ago and was initially successful, but the cancer came back. Or maybe one type of treatment stopped working and the cancer continued to grow. When this happens, your doctor may say that the cancer has progressed. There may or may not be other treatment options, but when many different treatments have been tried, and they no longer control the cancer, it may be time to weigh the benefits and risks of continuing to try new treatments.

It is very important to talk to your doctor and your cancer care team, and to trust that they are honest, upfront and supportive. You will have more confidence in treatment decisions if you trust your doctors’ recommendations. This means that communication is a key part of your care, from diagnosis, throughout treatment, and long afterward.

Try to avoid asking your doctor and your cancer care team questions like, “What would you do?” or “If you were in my place, would you try another treatment?” Instead of these questions, try asking the following questions, “Could you tell me all of my options?” and “Based on your experience in treating my type of cancer, what would you recommend?”

Urticaria is a disease of unknown origin and autoimmune in a percentage of cases, which is characterized by the presence of hives and wheals, produces intense itching throughout the day and can be associated with angioedema (swelling of the lips and eyelids).

The cells of the immune system have histamine granules in their interior; if histamine is released, it stimulates the nerve fibers of the skin and causes itching. The contact of histamine with the blood vessels causes them to release fluid which accumulates in the skin and causes wheals. If deeper layers are affected, angioedema occurs.

If this swelling is very intense, it can produce a complete deformation of the face. It lasts at least two and a half months. It produces an important alteration of the quality of life. The skin lesions appear without interruption.

In 50% of patients we have been able to demonstrate that it is an autoimmune mechanism, i.e. the body itself activates the skin cells which cause them to release histamine and produce urticaria.

External beam radiation therapy comes from a machine that focuses radiation on your cancer. The machine is large and can be noisy. It does not touch you, but it can move around you and send radiation to a part of your body from many directions.

External beam radiation therapy is a local treatment, which means it treats a specific part of your body. For example, if you have cancer in your lung, you will have radiation only to your chest, not your entire body.

Internal radiation therapy with a solid source is called brachytherapy. In this type of treatment, seeds, strips or capsules containing a radiation source are placed in the body in or near the tumor. Like external beam radiation therapy, brachytherapy is a local treatment and treats only a specific part of the body.

Radiation therapy can be expensive. It uses complex machines and involves the services of many medical providers.    The exact cost of your radiation therapy depends on the cost of medical care where you live, the kind of radiation therapy you receive and how many treatments you need.
