What is Cancer? Diagnosis, Treatment, and Risk Factors Guide

Cancer: Comprehensive Information About Diagnosis, Treatment, and Risk Factors

Cancer is the uncontrolled proliferation of cells in the body and the spread of these cells to surrounding tissues. While healthy cells have regulated lifespans and functions, cancer cells disrupt this balance and continue to multiply continuously. Cancer is a significant health problem affecting millions of people worldwide and causing deaths. In this article written for you, we will provide general information about cancer, oncology, cancer types, and risk factors in cancer.

What is Oncology?

Oncology is the branch of science dealing with cancer and includes work related to the diagnosis, treatment, and prevention of cancer. Oncologists are specialist doctors involved in treating cancer patients. Oncology is divided into subspecialties such as radiation oncology, medical oncology, and surgical oncology. Radiation oncology uses radiation to destroy cancer cells, while medical oncology uses methods such as chemotherapy and medications in cancer treatment. Surgical oncology deals with the surgical removal of cancerous tissues.

What are Cancer Types?

Cancer types are classified according to their origin and cell type. The main cancer types are as follows:

Carcinomas: A type of cancer originating from epithelial cells. Breast, lung, colon, pancreatic, and prostate cancers fall into this group.

Sarcomas: A type of cancer beginning in connective and supporting tissues, bone, cartilage, fat, and muscle tissue.

Lymphoma and myeloma: Cancer types beginning in the lymphatic system and bone marrow. Lymphoma begins in lymph nodes, while myeloma begins in plasma cells.

Leukemia: A type of cancer beginning in blood cells and bone marrow.

Brain and nervous system cancers: Cancers beginning in the central nervous system and brain.

What are Risk Factors in Cancer?

Genetic and environmental factors play a role in cancer development. Risk factors in cancer can be listed as follows:

• Age,

• Genetic predisposition,

• Tobacco and alcohol use,

• Diet and physical activity,

• Viral and bacterial infections,

• Exposure to radiation and chemical substances,

Cancer is a complex disease that develops due to the effects of many factors. Early diagnosis and appropriate treatment methods can improve quality of life and survival time. For this reason, regular health check-ups and reduction of risk factors are of great importance.

How Does Cancer Spread?

Cancer is a disease that results from uncontrolled and abnormal proliferation of cells in the body. Cancer cells initially form a tumor and grow locally. Later, these cells can spread to other areas of the body through the blood and lymphatic systems. The process of cancer spreading is called metastasis and occurs more frequently in advanced stages of cancer.

Three main mechanisms are involved in the cancer spreading process:

Local spread: Cancer cells directly spread to surrounding tissues and organs and grow. This process can damage surrounding tissues and organs.

Spread through the lymphatic system: Cancer cells can enter lymph nodes and then the lymphatic system, spreading to other areas of the body. Lymph nodes play an important role in fighting infection and disease by filtering lymph fluid in the body. The accumulation of cancer cells in lymph nodes can cause disease progression and lymph node enlargement.

Spread through blood circulation: Cancer cells can enter blood vessels and be transported to other areas of the body. This process results in cancer cells reaching distant organs, forming new tumors, and advancing the disease.

What are Cancer Symptoms?

Early signs of cancer can vary depending on the cancer type and stage of the disease. Some common cancer symptoms are as follows:

• Swelling or lump,

• Pain,

• Skin changes,

• Loss of appetite and weight loss,

• Fatigue,

• Bleeding and bruising,

• Infections,

• Digestive problems,

• Respiratory problems,

What are Rare Cancer Symptoms?

There are also rare symptoms of cancer, and these symptoms can vary depending on the cancer type and stage of disease. Rare cancer symptoms can be listed as follows:

• Cancer can cause neurological symptoms such as headache, vision disorders, balance problems, and seizures.

• Cancer can cause hormonal imbalances and consequently weight changes, skin problems, and mood changes.

• Cancer can cause bone pain and weakening, leading to fractures.

• Cancer can cause urinary problems, sexual dysfunction, and infertility.

• Cancer can cause color changes, rashes, and peeling in the skin and nails.

Cancer symptoms can also indicate other health problems. Therefore, when experiencing any of these symptoms, it is important to consult a healthcare professional for definitive diagnosis.

How is Cancer Diagnosed?

Cancer is the general term for diseases resulting from uncontrolled and abnormal proliferation of cells in any part of the body. Cancer diagnosis is performed using different methods depending on the cancer type and stage. Some methods used for cancer diagnosis can be explained as follows:

The doctor performs a physical examination to check whether there are any abnormalities in the patient's body. This is done to detect swellings, lumps, or skin changes.

Examination of samples taken from blood, urine, and other body fluids is necessary for cancer diagnosis. These tests can help detect the presence of cancer cells or cancer-related proteins.

Imaging tests such as X-ray, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and ultrasound help doctors determine the location and size of cancer cells.

Biopsy is the most accurate method for cancer diagnosis. Doctors take a small tissue sample from a suspicious area and examine it under a microscope to check for the presence of cancer cells.

Some cancer types develop due to genetic mutations. Genetic tests can help determine the origin of the disease and assess the risk in family members.

What is Cancer Staging?

Cancer staging is a system used to determine how widespread cancer is and whether it has spread to other areas of the body. Cancer staging helps predict the course of the disease, determine the treatment plan, and compare treatment outcomes in patients. Cancer staging is generally as follows:

Stage 0: Cancer cells are present only at the origin and have not spread to surrounding tissues.

Stage I: Cancer cells affect a small area at the origin and have not spread to surrounding tissues.

Stages II and III: Cancer cells affect a larger area and have spread to surrounding tissues and/or lymph nodes.

Stage IV: Cancer cells have spread to other areas of the body and is called metastatic cancer.

What is Metastasis?

Metastasis is the process of cancer cells spreading from their origin to other areas of the body. Cancer cells can move through the body via blood circulation or the lymphatic system and form new tumors. Metastasis is an important factor that determines cancer stage and treatment options.

Metastatic cancer usually requires more aggressive treatment and has a worse prognosis. Prevention and control of metastasis is an important goal in cancer treatment. Treatments aimed at preventing or delaying the spread of cancer cells may include chemotherapy, radiotherapy, immunotherapy, and targeted therapy.

Cancer Treatment: Various Methods and Processes

Cancer is a disease caused by uncontrolled proliferation and growth of cells in the body. Cancer treatment varies depending on the cancer type, stage, patient's general health status, and age. This article provides information about basic methods used in cancer treatment.

Surgery

Surgical treatment is the physical removal of cancer cells and tumors from the body. Healthy tissue surrounding cancerous tissue may also be affected, and this can help prevent disease recurrence. Surgery is particularly an effective treatment method when cancer is in early stages. However, in some cases, surgical intervention may be necessary even in advanced stages of cancer.

Radiotherapy

Radiotherapy uses high-energy radiation to destroy or shrink cancer cells. This treatment method damages the DNA of cancer cells, preventing their proliferation. Radiotherapy can be effective when cancer is concentrated in a specific area. This treatment can be applied before or after surgery, with chemotherapy, or as a standalone treatment.

Chemotherapy

Chemotherapy is a treatment method performed using medications that inhibit the growth and proliferation of cancer cells. These medications can help shrink tumors, prevent cancer spread, or alleviate disease symptoms. Chemotherapy can be administered as oral tablets or intravenous medications. This treatment is usually performed in cycles with time for the body to recover between cycles.

Immunotherapy

Immunotherapy is a treatment method that strengthens the body's immune system to help it fight cancer cells. This treatment works by increasing the number of immune cells that recognize and destroy cancer cells or by making cancer cells more visible to the immune system. Immunotherapy can be used in treating various cancer types and can be applied along with other treatment methods.

Targeted Therapy

Targeted therapies focus on specific molecules or intracellular processes that are important for the growth and proliferation of cancer cells. This treatment method causes damage to cancer cells while causing less damage to healthy cells. Targeted therapies are usually used in treating advanced stage cancers or when other treatment methods are ineffective.

Hormone Therapy

Hormone therapy is a treatment method aimed at preventing the growth and spread of hormone-sensitive cancer types. This treatment works by reducing hormone levels in the body or blocking cancer cells' ability to respond to hormones. Hormone therapy is particularly effective in hormone-sensitive cancer types such as breast cancer and prostate cancer.

Methods used for cancer treatment vary depending on the cancer type, stage, and patient's condition. These treatments are applied alone or together to bring cancer under control, alleviate symptoms, and improve the patient's quality of life. During cancer treatment, it is important for patients to maintain close communication with their doctors and adhere to the treatment plan.
