Lung Cancer: Diagnosis, Treatment, and Support

Spread the love

Lung cancer, prostate cancer, colorectal cancer, and stomach cancer are among the most common types of cancer in males worldwide.

According to the World Health Organization, lung cancer is the most common cancer in males, accounting for about 14.5% of all new cancer cases in men. Prostate cancer is the second most common, accounting for about 13.5% of new cases. Colorectal cancer is the third most common, accounting for about 9.7% of new cases, and stomach cancer is the fifth most common, accounting for about 6.8% of new cases.

The most common types of cancer can vary depending on geographic location, lifestyle factors, and other variables. Therefore, it is important to consult with a healthcare provider to determine an individual’s risk factors for developing cancer and to develop a personalized cancer screening and prevention plan.

Types of Lung Cancer

There are two main types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

Non-small cell lung cancer (NSCLC): This is the most common type of lung cancer, accounting for about 80-85% of all cases. NSCLC includes several subtypes, such as adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.

Adenocarcinoma: This is the most common subtype of NSCLC and usually develops in the outer regions of the lungs. It is often seen in non-smokers and can be caused by exposure to certain chemicals or substances.
Squamous cell carcinoma: This subtype typically develops in the central part of the lungs and is strongly linked to smoking.
Large cell carcinoma: This is a less common subtype of NSCLC and can appear in any part of the lungs.

Small cell lung cancer (SCLC): This type of lung cancer accounts for about 10-15% of all cases. SCLC is a fast-growing cancer that tends to spread quickly to other parts of the body. It is strongly linked to smoking.

The treatment options for NSCLC and SCLC differ due to the differences in the way these cancers grow and spread. Therefore, accurate diagnosis and staging of lung cancer is critical for developing an effective treatment plan.

Diagnosis

The diagnosis of lung cancer typically involves several steps, including a medical history and physical exam, imaging tests, and biopsy.

Medical history and physical exam: A doctor will typically ask about any symptoms or risk factors for lung cancer, such as smoking history, exposure to certain chemicals or substances, and a family history of cancer. They will also perform a physical exam, including listening to the lungs with a stethoscope.
Imaging tests: Imaging tests, such as chest X-rays, CT scans, and PET scans, are often used to detect lung cancer and determine its size and location. These tests can also help determine whether the cancer has spread to other parts of the body.
Biopsy: A biopsy involves taking a sample of tissue from the lung to examine under a microscope. This is typically done using a needle or during a procedure called a bronchoscopy, which involves passing a thin, flexible tube with a camera through the mouth or nose and into the lungs. The biopsy can help confirm the diagnosis of lung cancer and determine the type of cancer.

Once the diagnosis of lung cancer is confirmed, additional tests may be done to determine the stage of the cancer and help guide treatment decisions. These tests may include additional imaging tests or procedures to examine lymph nodes or other organs in the body.

Several other conditions can be confused with lung cancer, and accurate diagnosis is important for developing an effective treatment plan. Here are some examples:

Pulmonary nodules: These are small, round growths in the lungs that are often detected during imaging tests, such as chest X-rays or CT scans. While many pulmonary nodules are benign (non-cancerous), some can be early-stage lung cancer. Additional imaging tests, such as PET scans, and/or biopsy may be needed to determine if a pulmonary nodule is cancerous.
Tuberculosis (TB): TB is an infectious disease that can affect the lungs and cause symptoms similar to lung cancer, such as coughing, chest pain, and weight loss. Imaging tests may show abnormalities in the lungs that can be confused with lung cancer. A sputum test or biopsy can help diagnose TB.
Chronic obstructive pulmonary disease (COPD): COPD is a group of lung diseases, including chronic bronchitis and emphysema, that can cause breathing difficulties and lung damage. These conditions can increase the risk of lung cancer, and symptoms may be similar to those of lung cancer, such as coughing and shortness of breath. Additional testing, such as imaging tests and biopsy, may be needed to differentiate between COPD and lung cancer.
Other types of cancer: Cancer that has spread (metastasized) from another part of the body to the lungs can sometimes be mistaken for lung cancer. Additionally, some cancers, such as lymphoma, can start in the lymph nodes in the chest and cause symptoms similar to lung cancer.

Overall, an accurate diagnosis of lung cancer requires careful evaluation of symptoms, imaging tests, and biopsy results, and may require consultation with multiple medical specialists.

Specialists

There are several medical specialists who may be involved in the diagnosis and treatment of lung cancer, depending on the specific circumstances of each case. Here are some examples:

Pulmonologist: A pulmonologist is a medical specialist who focuses on lung diseases, including lung cancer. They may perform procedures such as bronchoscopy, in which a thin, flexible tube with a camera is inserted into the lungs to collect a tissue sample for biopsy.
Radiologist: A radiologist is a medical specialist who interprets medical images, such as X-rays, CT scans, and PET scans, to help diagnose lung cancer and determine its stage.
Medical oncologist: A medical oncologist is a doctor who specializes in the diagnosis and treatment of cancer with chemotherapy and other medications.
Radiation oncologist: A radiation oncologist is a doctor who specializes in using radiation therapy to treat cancer.
Thoracic surgeon: A thoracic surgeon is a doctor who specializes in surgery of the chest, including the lungs. They may perform surgeries such as lobectomy or pneumonectomy to remove cancerous tissue.
Pathologist: A pathologist is a medical specialist who examines tissue samples under a microscope to help diagnose cancer and determine its type.
Oncology nurse: An oncology nurse is a registered nurse who specializes in caring for patients with cancer, including those with lung cancer. They may help with treatment, symptom management, and emotional support.

In general, the diagnosis and treatment of lung cancer is a team effort that involves multiple medical specialists working together to develop an individualized treatment plan for each patient.

The person in charge of the treatment of lung cancer may vary depending on the specific circumstances of each case, but it is typically a medical oncologist, a radiation oncologist, or a thoracic surgeon. In some cases, multiple specialists may work together to develop and implement a comprehensive treatment plan.

Medical oncologist: A medical oncologist is a doctor who specializes in the treatment of cancer with chemotherapy and other medications. They may be in charge of developing and overseeing the chemotherapy regimen for the patient with lung cancer, and may collaborate with other specialists to determine the best treatment approach.
Radiation oncologist: A radiation oncologist is a doctor who specializes in using radiation therapy to treat cancer. They may be in charge of developing and overseeing the radiation therapy plan for the patient with lung cancer, and may collaborate with other specialists to determine the best treatment approach.
Thoracic surgeon: A thoracic surgeon is a doctor who specializes in surgery of the chest, including the lungs. They may be in charge of performing surgery to remove the cancerous tissue from the lungs, and may collaborate with other specialists to determine the best treatment approach.

In addition to the specific medical specialist in charge of the treatment, the patient with lung cancer may also work closely with other members of their healthcare team, such as a nurse navigator, social worker, or nutritionist, to manage symptoms, address emotional needs, and optimize overall health and well-being.
