What to Expect When You Visit an Oncologist
An oncologist is a medical doctor who specializes in the diagnosis, treatment and prevention of tumors. The field of oncology is classified as the study of tumors, both noncancerous (benign) and malignant (cancerous). Cancer is defined as a group of diseases caused by malformed or defective cells that cause uncontrolled replication or cell growth. This abnormal cell growth often forms a tumor. Different types of cancer have different causes, as well as occurrence rates.
Hundreds of different types of cancer have been discovered, and some oncologists specialize in certain types. An oncologist can treat both benign and malignant forms of cancer. Benign forms of cancer are relatively harmless - they’re localized and don't travel to other parts of the body. Malignant forms of cancer do ‘migrate’ or metastasize, traveling to other parts of the body through the blood or lymph system, which can wreak havoc on a single organ or multiple organ tissues in the body.
Staging and Grading Cancer
An oncologist is capable of determining severity of cancers through a process known as grading or staging. That means your oncologist may determine the level of severity of the cancer or cancerous cell growth, which in most cases, ranges from Grade 1 to Grade IV, with a higher grade meaning more severity or spread. The oncologist is also capable of staging the cancer, which means determining time rate and diagnosis based on its size and spread from its point of origin. Your oncologist may determine staging through a variety of diagnostic techniques known as clinical staging. Staging can range between Stage One, Stage Two, and Stage Three, depending on the depth, size and spread of the cancer cell or tumor growth.
Your oncologist may also diagnose, grade and stage various forms of cancer through the study of tumor marker tests, which measure levels of a number of biochemical substances found in body tissues, urine, and blood. Tumor marker tests may determine the presence of cancerous growth in organs in the body before other signs or symptoms may be present.
The oncologist may also utilize biopsy methods, which involve testing a sample of suspect tissue for tumor markers as well as a visual signs of abnormal cell development and growth. Imaging is also an effective method of diagnosing cancer, especially through the use of computed tomography (CT) scans, magnetic resonance imaging (MRI scans), as well as radiography, such as those commonly utilized to perform breast mammograms. Nuclear scans are especially beneficial in determining the location and stage of cancer in bone tissues.
During your visit to an oncologist, be prepared for a complete and detailed physical history. The doctor will ask whether you smoke, or have been (or are) exposed to potential cancer-causing agents or scenarios. The doctor will also ask for information about your diet, or about other family members who may have been diagnosed with cancer to determine genetic risk of certain types of cancer. The doctor will then take request blood tests that will help him or her determine the level of biochemical substances in the blood, urine or tissues that may indicate cancer, including tumor markers, and may then request a biopsy, diagnostic imagery, or a combination of all the above processes to determine an accurate and effective diagnosis.
Following diagnosis of cancer i.e lung cancer, your oncologist will offer a number of therapeutic interventions that will be based on your specific diagnosis, situation, age, and overall health. Interventions may include surgery, radiotherapy(radiation), systemic therapy, which includes chemotherapy, bone marrow transplants, and immunotherapy, or a combination, depending on your specific case and the severity of the cancer.
