father had passed away from brain cancer. We were devastated because he was battling with it for six years, some of the hardest years of my life. E – He passed away in 2015, and a month before he had passed away, he was diagnosed with brain cancer for the third time and we were told from the doctors that he would live only 3 months. Prior to this, he had brain cancer in 2009 and it was removed by a successful surgery. Then in 2010, he was diagnosed with cancer again and he had chemotherapy. This

Cancer cells are characterized by unlimited cell growth, inefficient apoptosis and excessive anabolism. The process of becoming cancer cells includes gene activation, micro-environmental changes and metabolic reprogramming. All of which compound upon one another and lead the cancer cells to continue with their overwhelming growth and activity. Malignant cancer cells invade and destroy organ infrastructure and replace it with disorganized and damaging cells. (1) The metabolic preference of cancer

some types of brain cancer do not show any signs or symptoms, the ones that do depend on many factors such as the type itself, size, location, and maybe sometimes age, health history, which part is involved, and which functional system is affected. Because of the numerous factors, symptoms may vary among patients. The most frequent symptoms are headaches, seizures, and weakness and/or numbness. Vision changes as well as loss of motor skills are also signs of a growing brain cancer, depending on the

Cancer is a collection of diseases that are caused by the division of abnormal cells that spread to other areas and tissues of the body, growing uncontrollably and forming a mass of tissue called a tumor. It is a genetic disease, causing changes to our genes to control the way cells function, grow, and divide, and can be inherited from our parents as well as resulting from environmental exposures such as UV rays, radiation, and smoking. While there are many successful treatments to help treat and

regulatory systems prevent uncontrolled cellular proliferation. In other words, cells only take up nutrients from their environment upon stimulation by growth factors. By acquiring mutations that alter the receptor-initiated signaling pathways, cancer cells are able to overcome the growth factor dependence exhibited by normal cells. These oncogenic mutations promote the uptake of nutrients, particularly glucose, and lead to improved cell survival and growth [1,3]. The realization that cancerous

Title: Targeted Therapy in Ovarian Cancer Authors: Hui Jun, Lim1 and William, Ledger2 Affiliations: University of New South Wales, Australia1, School of Women and Children’s Health, Prince of Wales Hospital, Sydney, Australia2   Abstract Among female-specific cancers worldwide, ovarian cancer is the leading cause of death from gynaecologic malignancy in the Western world. Despite radical surgery and initial high response rates to first-line chemotherapy, up to 70% of patients experience relapses

bladder. A few weeks later the test results came back positive for cancer. In the past two years I have watched my dad go through many changes that were sad to observe as a daughter, but interesting to learn about as a future medical student. Although I do not know what type of bladder cancer my dad has, I do know he is in stage T1 of his cancer. My dad is doing better as of now, but I have always wanted to learn more about his cancer, and this assignment as given me that chance. Anatomical Structure

What is Cancer? Cancer is many diseases which involve abnormal cell growth. Cancer cells are able to replicate and spread because they completely lose control and are not able to be restrained. These cells will then form to become tumors. There are two types of tumors called malignant and benign. The malignant tumor is the cancerous tumor. The benign tumors are much less destructive to the body. To tell the difference is quite simple, a malignant tumor has the ability to spread through metastasis

INTRODUCTION Kidney cancer is a metabolic disease; comprised of several cancers in the kidney, each with a different histology and clinical course (Linehan, 2011). Kidney cancer occurs when abnormal kidney cells uncontrollably proliferate, developing into aggressive tumours that may metastasize to other parts of the body. GENERAL OVERVIEW In 2013, kidney cancer was the 9th most commonly diagnosed cancer in Australia, producing 3,059 new cases of kidney cancer, in which 1,987 were male and 1,071

While there are different types of bone cancers, the symptoms for each are generally about the same with the severity varying with the size and location of the tumor (Upstate Medical University, 2014). The most common symptom is pain, which, in the case of cancers such as osteosarcoma, chondrosarcoma, and Ewing’s sarcoma, may occur in the arms, legs, and knees. The pain may start out as being infrequent and only occur at night or when the bone is in use. Over time, as the tumor grows, the pain
