OVER THE PAST DECADE, lung cancer treatment has changed dramatically, especially for patients who have advanced stage disease. Many patients now benefit from a better understanding of what drives tumors to develop and grow and how they interact with our immune system and the surrounding environment. This has led to advances in areas of immunotherapy and targeted therapies.

Immunotherapy

Our body's immune system recognizes things that may be dangerous – such as certain bacteria, viruses and cancer cells – and works hard behind the scenes to keep them from causing us harm.

Cancer is good at tricking the immune system, however. It can make it difficult for the immune system to recognize cancer as harmful, so it doesn't attack and destroy the cancer cells.

Leukemia is a cancer of the blood or bone marrow. Bone marrow produces blood cells. Leukemia can happen when there is a problem with the production of blood cells. It usually affects the leukocytes, or white blood cells.

It is most likely to affect people over the age of 55 years, but it is also the most common cancer in those aged under 15 years.

In the United States, 62,130 people are expected to receive a diagnosis of leukemia in 2017, and around 24,500 deaths will likely be due to this disease.

Acute leukemia develops quickly and worsens rapidly, but chronic leukemia gets worse over time.

Scientists have engineered a new kind of antibody that attaches itself to cancer cells before summoning and activating killer T cells from the immune system to destroy them.

The immune system has many ways to protect the body against cells that grow out of control.

However, there are times when the rogue cells "overwhelm or evade" these natural defenses and give rise to cancer.

A new approach in cancer treatment, known as immunotherapy, is developing therapies that can give the immune system a helping hand.

Colorectal cancer is the fourth most commonly diagnosed type of cancer in the United States. Though various treatments are available for it, certain tumor cells are therapy-resistant. Now, research suggests that an antifungal drug may be effective against these persistent cells.

The drug itraconazole is typically used in the treatment of fungal infections.

These can include certain types of vaginal yeast (vulvovaginal candidiasis) and fungal infections on the hands and feet (Tinea pedis and Tinea manuum).

But researchers from the Cancer Research UK Cambridge Institute have suggested a brand new use for this substance — namely, as a treatment that is able to eliminate dormant tumor cells in colorectal cancer.

According to a landmark study, a large percentage of individuals with the most common form of early breast cancer could safely skip chemotherapy. The findings could impact thousands of people each year.

While new therapies such as immunotherapies are becoming increasingly crucial in treating cancer, chemotherapy is still a mainstay.

In short, chemotherapy uses drugs to cure or control cancer throughout the body.

As opposed to surgery or radiation therapy — which concentrates on the tumor and the area surrounding it — chemotherapy will affect the whole body.

​Many of the symptoms of colorectal cancer can also be caused by something that isn’t cancer, such as infection, hemorrhoids, irritable bowel syndrome, or inflammatory bowel disease.

In most cases, people who have these symptoms do not have cancer. Still, if you have any of these problems, it is a sign that you should go to the doctor so the cause can be found and treated, if needed:

When you think of cancer treatments, chemotherapy and radiation probably come to mind. That may change soon.

A lot has happened in recent years to transform how the disease is, and will be, treated. As a result, folks with cancer and their doctors have more options to pick from, with more on the way.

Immunotherapy

One thing that makes cancer tough to fight is that its cells can dodge your immune system. Your body either doesn’t see them as threats, or it simply can’t work hard enough to fight them.

But new immunotherapy drugs “mark” these cells so that they’re easier to find. These medicines can also make your body's defenses stronger so they can attack tumors.
