Benign lung tumors don't spread to other areas of your body. Generally, benign tumors grow slowly, but they can sometimes stop growing or may even shrink. These tumors usually don't require removal or treatment and aren't life-threatening.
Benign lung nodules and tumors usually cause no symptoms. This is why they are almost always found accidentally on a chest X-ray or CT scan.
Lung masses can be benign (non-cancerous) or malignant (cancerous). In most cases, lung masses are cancerous. The primary goal of your doctor is ensure that your lung mass is not malignant.
Patients can (and usually do) live with lung cancer for many years before it becomes apparent. Early lung cancer is largely asymptomatic and internalisation of tumours means patients are not alerted by obvious physical changes.
Because there are very few nerve endings in the lungs, a tumor could grow without causing pain or discomfort. When symptoms are present, they are different in each person, but may include: A cough that doesn't go away and gets worse over time. Hoarseness.
A non-cancerous (benign) tumour of the lung is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are usually not life-threatening.
How common are benign lung nodules? Pulmonary nodules are fairly common. They are seen in about one of every 500 chest X-rays and in about one out of every 100 chest CT scans. At least 60% of pulmonary nodules seen on chest X-rays turn out to be benign, and 99% of those on chest CT are benign.
On average, lung cancers double in size in four to five months.
When a benign tumor must be removed surgically, there are now minimally invasive procedures that allow for a much faster recovery. The procedure known as video-assisted thoracoscopic surgery involves making a few incision in the chest wall in order to gain access to the lungs.
In general, a lung nodule can be removed very safely and using a minimally invasive surgical approach. Your surgeon may want to perform a bronchoscopy to take a closer look at your nodules and take a biopsy. A biopsy involves removing a piece of your lung to look at it under a microscope.
Benign nodules are almost always healed over “wounds” on the lung left from tuberculosis or a fungal infection, although there are other, less common causes. Cancerous nodules can be the first stage of a primary lung cancer, brought on by smoking or any other common cause of lung cancer.
When an infection or illness inflames lung tissue, a small clump of cells (granuloma) can form. Over time, a granuloma can calcify or harden in the lung, causing a noncancerous lung nodule. A neoplasm is an abnormal growth of cells in the lung. Neurofibromas are a type of noncancerous neoplasm.
Even though most benign tumors are harmless and can be left alone, it's important they be monitored. And any tumor that is painful or growing requires a visit to the doctor.
Benign lung nodules can be caused by inflammation from a number of conditions. They include: Bacterial infections, such as tuberculosis and pneumonia. Fungal infections, such as histoplasmosis, coccidioidomycosis or aspergillosis.
Benign tumors are not usually problematic. However, they can become large and compress structures nearby, causing pain or other medical complications. For example, a large benign lung tumor could compress the trachea (windpipe) and cause difficulty in breathing. This would warrant urgent surgical removal.
For brain or lung metastasis, the larger the tumor, the higher the risk of brain or lung metastasis.
In other cases, the cancer may have reached the lymph nodes in the same area of the chest as the original tumor—typically, the lymph nodes near the bronchus or within the lung. In addition, the cancer meets one of the following criteria: The lung cancer tumor is larger than 7 cm.
Nodules between 6 mm and 10 mm need to be carefully assessed. Nodules greater than 10 mm in diameter should be biopsied or removed due to the 80 percent probability that they are malignant. Nodules greater than 3 cm are referred to as lung masses.
The five-year survival rate for lung cancer is 56 percent for cases detected when the disease is still localized (within the lungs). However, only 16 percent of lung cancer cases are diagnosed at an early stage. For distant tumors (spread to other organs) the five-year survival rate is only 5 percent.
It's rare for cancer to go away on its own without treatment; in almost every case, treatment is required to destroy the cancer cells. That's because cancer cells do not function the way normal cells do.
Chest pain, shortness of breath and a persistent cough can all be symptoms of lung cancer. But they can also be signs of other conditions, including heart problems, anemia and even a COVID-19 infection.
What is lung pain? Lung pain is often felt when you breathe in and out, either on one or both sides of your chest. Technically, the pain isn't coming from inside the lungs, since they have very few pain receptors. Instead, the pain may come from the lining of the lungs, which does have pain receptors.
Back pain is usually a dull ache in the lower back, which may radiate to the buttocks and legs. It can be caused by an injury or other conditions like arthritis or sciatica (nerve irritation). Lung pains are deep, stabbing pains that usually occur in the upper back near where your shoulder blades meet at your spine.
