  • Most people when they hear the word tumor think CANCER but that’s not always the case.

  • There are a lot of different types of tumors, or neoplasms as theyre called by medical

  • professionals. The two main types, benign, which means it stays as it is, and doesn’t

  • change and malignant, which signals something bad, like cancer, which means it can spread.

  • There’s a lot of tumor terminology. Names of tumors most often come from where they

  • grow. Like Adenomas come from epithelial tissue, which is a thin layer or membrane that surrounds

  • your organs. Fibroids grow on fibrous or connective tissue. Fibroma durum (hard fibroma) is a

  • common type, theyre those skin tags you get on your neck or armpit. Hemangiomas are

  • more like those strawberry birthmarks, they are just a collection of too many blood cells

  • in one place. These are often temporary and last just a few years in childhood.

  • Those are just the benign tumors. Carcinomas are cancerous tumors found in epithelial cells.

  • Sarcomas start off in connective tissue, such as cartilage and bones. Leukemia originates

  • in the marrow and generally mature in the blood or lymph nodes and Blastomas form from

  • embryonic tissue.

  • While they all go by different names, many tumors come from an overgrowth of tissues,

  • maybe caused by a mistake in DNA. DNA might be damaged from radiation, tobacco smoke or

  • other environmental agents, or maybe it’s just a stroke of luck. Whatever causes it,

  • this mutation makes the cell divide uncontrollably, basically making clones of themselves. As

  • the cells pile up, a tumor grows. If it grows big enough it can harm nearby organs and tissues

  • or sometimes a part of the tumor can break off and take up residence in other parts of

  • the body, which is when cancer metastasizes.

  • There’s another idea, that stem cells trigger tumors. These wonky stem cells drive tumor

  • growth and just like normal stem cells can give rise to differentiated cells. These stem

  • cells are especially good at resisting treatment like chemotherapy. Chemotherapy might wipe

  • out those differentiated cells, but leave the cancer stem cells behind, so they come

  • back stronger and in greater numbers.

  • And I mean chemotherapy is a brutal process, the first chemotherapy drugs were a derivative

  • of mustard gas.. But it does have the nifty ability to stop cell growth. Which is handy

  • when dealing with runaway cell growth. But it can also harm other type of cells that

  • grow a lot, like hair follicles. While modern drugs work in other ways, theyre still

  • pretty nasty. With the usual side effects of hair loss, fatigue, nausea, and a knocking

  • out of the immune system.

  • Another way we attack tumor cells is through radiation, where radiation beams are aimed

  • at a tumor and stop its growth by damaging DNA. While the immediate side effects are

  • minimal, it might feel like a sunburn. Other long-term effects might be more damaging.

  • And radiation isn’t 100% effective. Some tumor cells could get left behind, which is

  • a problem with surgery too.

  • Some of these treatments are nasty and painful and seem to leave the job unfinished. So why

  • haven’t we come up with anything better? Well thereve been some cool new ideas put

  • forward recently.

  • Researchers from Duke University are looking to treat tumors WITH POLIO. Polio, a horrible

  • virus, used to run rampant and kill thousands of people a year and paralyze thousands more

  • until the introduction of a vaccine in 1955. You’d think the world would never want to

  • see the disease again. Yet over the past few decades scientists have reengineered the virus

  • which seems to knock out a brain tumor’s defenses, allowing the patient’s immune

  • system to finish the job. GIVE THE DISEASE DISEASESWHOA.

  • Another new idea might make surgery a little easier. Some researchers from the Fred Hutchinson

  • Cancer Center in Seattle propose injecting people with scorpion venom. Alright, sounds

  • crazy I know, but bear with me. The venom is injected into the patient's blood stream,

  • crosses the blood-brain barrier, and makes its way into the brain tumor.

  • Tumor Paint, as it’s appropriately called consists of two parts. Scorpion venom has

  • to find it’s way to the prey’s brain to paralyze it. Turns out that same compound

  • binds really well the surface of brain tumor cells. The other part of Tumor Paint lights

  • up under fluorescent light. This could be huge. That way brain surgeons can see the

  • tumor literally glowing and see where the tumor stops and the healthy brain tissue starts.

  • But with any kind of new experimental treatment, it’s best to be cautious. Very cautious.

  • We hear the term CURE FOR CANCER in the news a lot, and sometimes we never hear another

  • word about those treatments again. It’s okay to be optimistic and skeptical at the

  • same time. AND REMEMBER: say it with me nowMORE RESEARCH IS NEEDED.
