What causes erectile dysfunction?
The erectile quality is in a serious risk for those whom alcohol and drugs (even those wrongly referred to as the passenger) is a daily part. Stress and fatigue that accompany nearly every modern man, as well as poor nutrition, lack of physical exercise and regular sleep starvation, are still a couple of reasons that will not make penis straighten oneself with delight every charming woman in front. Not because the man did not want to – he is simply tired. There is one more banal reason for erectile dysfunction – lack of interest. A man with whom one partner had a long-term cohabitation and / or sexual relationship with time could get a feeling of tolerance and indifference. Consequently, the decree, which is sent from the head of penis blood vessels are not fully transferred, and erections are partial or absent. When the irritation is powerful – a new partner or unusual circumstances may have – from a man in a full erection.

Erectile Disfunction

In some cases, particularly characterized by younger men, erectile disorder could be caused by pituitary tumor. Are not malignant, and it is easily curable with drugs, but one of the hormones it produces, aggravated by the erection. Like many who use drugs for blood pressure, the shy to discuss erectile dysfunction with cardiology or other doctors, who extract medicines. However – if the erection problems, bashfulness throw at the edge, and your problem should be entrusted to a specialist.

After liver cancer is found and staged, your doctor will recommend one or more treatment options. Choosing a treatment plan is a major decision. Take time and think about all of your choices.

When planning your treatment, it is important to take into account is the stage (extent) of the cancer. But you and your cancer care team will also want to think about your age, general state of health, and personal preferences.

It may be a good idea to get a second opinion, especially from a doctor experienced in treating liver cancer. A second opinion can give you more information and help you feel more confident about the treatment plan that you pick. Some insurance companies want a second opinion before they will agree to pay for certain treatments. Almost all will pay for the second opinion.

Surgery

At this time surgery offers the only likely chance to cure liver cancer. Surgery is done either to remove the tumor or do a liver transplant. If all of the cancer that the surgeon can see at the time of the operation can be removed, you have the best outlook for survival. But complete removal of most liver cancers is not possible. Often the cancer is large, is found in many different parts of the liver, or has spread beyond the liver. Also, many people with cirrhosis do not have enough healthy liver left to make surgery an option.

Your liver is the largest organ inside your body. It filters harmful substances from the blood, digests fats from food and stores the sugar that your body uses for energy. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver.

Risk factors for primary liver cancer include

* Having hepatitis
* Having cirrhosis, or scarring of liver
* Being male
* Low weight at birth

Cancer symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms and the liver cancer may not be found until it is advanced. This makes it harder to treat. Liver cancer treatment options include surgery, radiation, chemotherapy or liver transplantation.

Modern three-dimensional radiation therapy has been proven to be more successful at curing lung cancer than older two-dimensional radiation therapy for some patients with early stage lung cancer, according to a new study in the September 1, 2006 edition of the International Journal of Radiation Oncology * Biology * Physics, the official journal of the American Society for Therapeutic Radiology and Oncology (ASTRO).

Non-small cell lung cancer (NSCLC) accounts for 87 percent of all lung cancers diagnosed. Currently, the best treatment for stage I NSCLC is surgery or stereotactic radiation therapy (SRT), often followed by chemotherapy if the lesion was larger than 3 cm or radiotherapy and chemotherapy if the surgical margin or hilar or mediastinal nodes were positive at the time of operation. The five-year survival outcomes are very high, with 50 to 67 percent of these patients living at least five years after diagnosis if patients had a well staged stage I NSCLC. When surgery is not an option because the patient has heart problems or other complications, treatment options include varying types of radiation therapy and chemotherapy, alone or in combination.

In this study, doctors at M.D. Anderson Cancer Center in Houston wanted to see if conventional radiation therapy worked as well as the newer three-dimensional conformal radiation therapy (also called 3D-CRT) at curing patients with early stage non-small cell lung cancer. 3D-CRT was created to improve upon older types of radiation therapy by allowing doctors to aim several radiation beams at the tumor to shape or “conform” the radiation to the lung. The idea is that tailoring each beam allows doctors to give more radiation to the tumor while keeping it away from nearby healthy tissues.

Between 1978 and 2003, 200 patients with medically inoperable stage I NSCLC were treated with radiation therapy alone. Eighty-five received 3D-CRT while 115 received conventional therapy. Thirty-six percent of patients who received 3D-CRT lived five years after diagnosis compared to 10 percent who received the conventional therapy. Their causes of deaths were more related to intercurrent disease rather than cancer. Local failure was significantly reduced by 3D-CRT compared to conventional RT.

“This study proves that three-dimensional conformal radiation therapy improves outcomes for patients with medically inoperable stage I non-small cell lung cancer,” said Ritsuko Komaki, M.D. “Patients with this type of lung cancer should ask their radiation oncologist about 3D-CRT.” Dr. Komaki is a radiation oncologist and professor at M.D. Anderson Cancer Center in Houston.
