As you know that, the cells are building blocks of your body and they tend to multiply for the normal growth. But when cells multiplied in an uncontrolled manner these cells gives rise to the problem known as cancer. It can be seen that cancer is becoming one of the major issues related to the health in today's scenario because number of people affecting by cancer is keep on increasing day by day & it can develop in part of the body such as lung, colon, breast or skin, bones or nerve tissues. Moreover, there can be many causes of cancers including:
• Benzene and other chemicals.
• Drinking excess alcohol.
• Environmental toxins, such as certain poisonous mushrooms and a type of poison that can grow on peanut plants (aflatoxins).
• Excessive sunlight exposure.
• Genetic problems.
• Obesity.
• Radiation.
• Viruses
Symptoms of cancer mainly depend on the type and location of the cancer. For illustration, lung cancer can cause coughing, shortness of breath, or chest pain, while Colon cancer often causes diarrhea, constipation, and blood in the stool. In certain cases some cancers may not have any symptoms at all such as pancreatic cancer; symptoms often do not start until the disease has reached an advanced stage.
In addition, seeking all these cancer causes and symptoms there are basically three main types of treatment available for treating cancer that is: surgery, radio therapy, chemo therapy. Hence, surgical specialty dealing with cancer management and the study related to cancer treatment is termed as oncology.
Oncology is concerned with:
• The diagnosis of any cancer in a person• Therapy (e.g., surgery, chemotherapy, radiotherapy and other modalities)
• Follow-up of cancer patients after successful treatment
• Palliative care of patients with terminal malignancies
• Ethical questions surrounding cancer care
• Screening efforts:
o of populations, or
o of the relatives of patients (in types of cancer that are thought to have a hereditary basis, such as breast cancer)
The most important diagnostic tool remains the medical history: the character of the complaints and any specific symptoms (fatigue, weight loss, unexplained anemia, fever of unknown origin, paraneoplastic phenomena and other signs). Often a physical examination will reveal the location of a malignancy.
Diagnostic methods include:
• Biopsy, either incisional or excisional;• Endoscopy, either upper or lower gastrointestinal, bronchoscopy, or nasendoscopy;
• X-rays, CT scanning, MRI scanning, ultrasound and other radiological techniques;
• Scintigraphy, Single Photon Emission Computed Tomography, Positron emission tomography and other methods of nuclear medicine;• Blood tests, including Tumor markers, which can increase the suspicion of certain types of tumors or even be pathognomonic of a particular disease.
• Benzene and other chemicals.
• Drinking excess alcohol.
• Environmental toxins, such as certain poisonous mushrooms and a type of poison that can grow on peanut plants (aflatoxins).
• Excessive sunlight exposure.
• Genetic problems.
