The doctors at INTEGRIS are widely considered some of the best at treating cancer in Oklahoma. Our team brings decades of experience diagnosing and treating every type of cancer. We serve the entire state from our hospital locations in Oklahoma City, Yukon, Edmond, Enid, and Miami.

The INTEGRIS team is committed to providing the best care for its patients with lung cancer We believe this starts with education about the disease, its symptoms, and treatment.

Lung cancer most frequently begins in the lungs’ main passageway for air, the bronchi. From here, it may spread to other areas of the lungs or body. Lung cancer is the second leading type of cancer diagnosed and is the leading cause of cancer deaths. It is thought to develop over a period of many years.

Two main types of lung cancer exist, and each type behaves differently across the course of the disease. The most common type is non-small-cell cancer, comprising 80-90% of cases. Non-small-cell cancer has been delineated into three categories:

  • squamous cell carcinomas, which begin toward the center of the lungs
  • adenocarcinoma, which often starts toward the outer parts of the lungs
  • large cell carcinomas, which might initiate anywhere and often develop rapidly.

The second type of lung cancer is small-cell lung cancer. This form of lung cancer is known to grow and spread very quickly. Two forms of small-cell cancer have been identified:

  • Limited, wherein the cancer is found in only one lung and neighboring lymph nodes
  • Extensive, wherein the cancer has spread to other parts of the body.

Symptoms usually don’t present until the cancerous tumor has begun to grow. Although symptoms are experienced differently by each person, a number of symptoms are common:

  • A persistent cough
  • Constant chest pain
  • Difficulty breathing, wheezing
  • Repeated lung infections
  • Coughing up bloody mucus
  • Hoarseness
  • Swelling in the face or neck
  • Shoulder or bone pain
  • Pain or weakness in the shoulder, arm, hand or face
  • Fatigue or confusion
  • Loss of appetite and/or weight loss

These symptoms may not be sure signs of lung cancer, but could be signs of other medical concerns. Be sure to visit your doctor for an accurate diagnosis.

Each individual's treatment program is unique to him or her. Upon diagnosis, a plan is mapped out, taking into consideration the individual’s age, overall health and health history, the type of lung cancer, how much the cancer has advanced, predicted course of the disease, tolerance for available procedures and medications, as well as the person’s preferences and opinions.

In early-stage cases, treatment may include surgery. Depending on the size and location of the tumors, all or part of one lung could be removed, as well as a portion of the bronchus. Early and later-stage cancers may be treated with external or internal radiation therapy, chemotherapy, targeted therapy, and photodynamic therapy (PDT).
