Originally, the word Tumor, means “swelling”. Often times it is still used with this mean, but more so a Tumor meaning swelling is among the five major classic characteristics of imflammation. In modern science the term Tumor is primarily saved to denote the abnormal growth of tissue.
There are two major types of tumors: Malignant and Benign
Malignant Tumors are called also known as cancer. Cancer in this form has the readily available potential to invade and destory bordering tissues. Benign Tumors on the other hand do not invade the bordering tissues, or create metastases, rather they may localy grow to a great size. Under normal circumstances Benign Tumors will not return once they have been removed surgically.
The older a person gets the more mutations they have accumulated amongst their DNA, which makes them more prone to tumors. With that in mind, age is a factor, and with increasing age, the likelyhood of developing a tumor increases. Also known is that the older an individual who is affected with a tumor is, the higher the odds that the tumor will be malignant.
Tumors are causes by mutations that can occur in DNA of our bodies cells. A single mutation is not sufficient for a tumor to develop but rather an accumulation of multiple. The most common type of tumor that we hear about on a day to day basis is a “Brain Tumor”
AIDS. The very sound of the word scares some, and makes other cringe. How did we let it get so far? There is no cure for very few diseases, and aids is one of them. Yet we still have unprotected sex, and we still share dirty needles. Come on! Granted, HIV/AIDS will never be a thing of the past, but we can do better in making the condition less common.
HIV/AIDS kills. In 2004, it was responsible for 3.5 million deaths globally. Thats not even the worst of it. 6.4 million people newly contracted the virus in the same year! Instead of diminishing the deadly condition, we are multiplying it. This needs to stop. It’s as if 3.5 million wasn’t enough dead in 2004, so we decided to boost the numbers for 2005. What are we thinking?!
Mothers can share AIDS with their infants during pregnancy, childbirth, or breastfeeding, and there is no way to stop it short of not becoming pregnant. But here is the list of preventable HIV/AIDS transmissions:
- Penetrative oral, vaginal, or anal sex (Unprotected)
- Blood transfusion
- In health care settings
- Drug injection
So if these ways are all preventable, why is HIV/AIDS still such a major problem?
The human race needs to wise up, stop sharing needles, screen blood transfusions, and use condoms. Let’s beat AIDS before it beats us.
More than 145,000 new cases of colorectal cancer will be diagnosed in the United States. Colorectal cancer, which is the third most commonly diagnosed cancer in the country, is a disease in which malignant cells form in the colon or rectum. Unfortunately, colorectal cancer incidence and mortality rates have only moderately decreased or remained level over the past decade, and according to the American Cancer Society, more than 56,000 will succumb to the disease this year.
Important research is under way with the goal of improving treatment options for patients with colorectal cancer. There is a clinical trial being conducted around the country to investigate a potential new colorectal cancer treatment. The study, known as PACCE (Panitumumab Advanced Colorectal Cancer Evaluation), is a Phase 3 clinical trial designed to evaluate the effects of using two targeted cancer therapies in combination with chemotherapy for patients with colorectal cancer that has spread.
Across the country, institutions are currently enrolling patients in the PACCE trial, and there may be a trial site in your area. The treatments used in the study are chemotherapy, which kills cancer cells; a medication called bevacizumab, approved to stop the growth of blood vessels to the tumor; and panitumumab, an experimental treatment that is being investigated to see if it will help stop the tumor from growing. Patients who participate in the trial are treated either with chemotherapy and bevacizumab, or with panitumumab in addition to chemotherapy and bevacizumab.
