Metastasis in know as the spreading of cancer cells from one location in which the tumor is present to another part in the body. Metastasis is one major in distinguishing the difference between a benign or malignant tumor. Along with this metastasis is also a huge cause of why death occurs in cancer. In the absence of metastasis in a benign tumor‚ the cancer can be removed with chemotherapy or through surgery. Once cancer has metastasized it is not easy to remove it from the affected area.

of pulmonary metastasis with widespread progression that leads to respiratory failure. Tumor invasion and metastasis is multistep complex process in which tumor cells alter cell–extracellular matrix (ECM) interactions at the primary tumor site to invade adjacent tissues and thus translocate through the vasculature to other systems to form secondary tumors there. A family of proteolytic enzymes called MMPs are the key proteases playing an important role in tumor invasion and metastasis by degrading

changes occurring during the natural history of tumor growth and development. Genetic changes accumulate in the form of mutations‚ activation of proto-oncogenes‚ or the loss of tumor suppressor genes that could promote tumor progression‚ invasion‚ and metastasis; this process provides a rational basis for targeting one or more critical genetic defects in cancer cells by using gene-mediated therapy approaches(Parks & Bramson‚ 1999).

Once the SLN is localized‚ a suture is placed through the node to provide traction. The node is then dissected free from the surrounding tissue. All feeding blood vessels‚ afferent and efferent lymphatics may be ligated. Using the radiocolloid method‚ the gamma probe is used to locate any other SLNs and to confirm low radioactivity counts in the axilla and no residual SLNs. Ex vivo and in vivo radioactivity counts are recorded for each node. The axillary tissue is also carefully palpated for any

spread‚ it is called metastasis (3). Cancerous cells split from where they initially formed (primary cancer)‚ hitchhike through the framework of the blood or lymph system‚ and form new tumors (metastatic tumors) in different areas of the body. The metastatic cancer is not any different than the original cancer and tumor (4). For example‚ abnormal cells in the lung can travel to the bones and develop there‚ but it’s still classified as lung cancer. The reason cancer and metastasis is so dangerous is

very low at 30%. In advanced prostate cancer‚ metastasis occurs in distant organs such as the brain‚ liver‚ lungs‚ lymph nodes‚ and bone. Particularly‚ 90% of patients with advanced prostate cancer present metastasis in the bone. Both localized and advanced prostate cancers do not respond to standard chemotherapeutic interventions and thus require alternative treatments. (is treatment of bone mets only palliative? If so‚ it can be said here) Metastasis of prostate cancer cells initially depends on

Testicular cancer is a pain that involves the testes and it may cause a swelling or a lump that man or boys can feel or touch by themselves or they can go for a checkup with a doctor.

There has been debate over the exact mechanism of metastasis of the tumor cells from the stomach‚ appendix or colon to the ovaries.

Curcumin has been found to be a potent inhibitor of tumour growth and cell proliferation. This activity is linked to curcumin’s antioxidant effect and free radical scavenging effect (Akram et al‚ 2010). It inhibits cancer development and progression‚ thereby targeting multiple steps to malignancy. It has the ability to act like a blocking agent thereby inhibiting the initiation step of cancer by preventing the activation of carcinogen‚ and also as a suppressing agent thereby inhibiting malignant

SIGNIFICANCE Hepatocellular carcinoma (HCC) is the second leading cause of cancer-death in the world. In 2012‚ 782‚000 people were diagnosed and 95% mortality rate makes it the sixth most common cancer [1]. HCC in early stages is usually asymptomatic. When symptoms do occur they are usually mistaken for other liver diseases. Therefore‚ early diagnosis of HCC is extremely challenging. Surgical resection and liver transplant are the best treatment options for early stage HCC (BCLC stage 0 or A [2])

The body is combined of more than millions of cells. Cancer starts from defects or mutation in DNA of one cell or a slight number of cells. Mutations can happen by chance when a cell is dividing‚ or by chemicals from outside of the body such as skin lotion or ultraviolet. In addition‚ skin cancer is the uncontrolled growth of abnormal skin cell which has many stages‚ and it may spread to other organs. As skin cancer cells grow‚ they can group together to form a tumor.

Therefore a method needs to be developed that can detect BCC at the early stages to prevent late diagnosis of BCC which may lead to metastasis causing disabilities to patients and increasing treatment costs. In addition‚ BCC patients who have undergone surgery are still at risk for recurrence‚ especially when the surgery performed fails to
