When there is abnormal tissue growth in the lung organs, this is likely a lung tumor. Lung tumors can be benign, can also be malignant. This condition is important to detect early so the treatment success rate is higher.

During this time many people are mistaken about the definition of tumor. Some people consider tumors to be benign. Others believe tumors and cancer are the same thing. Actually the term benign or malignant depends on the nature of the tumor. It is said to be benign if the tumor tends to grow slowly and does not spread to other body parts. Meanwhile, malignant tumors tend to invade surrounding tissue and spread to other body parts. This malignant tumor is actually called cancer.

Distinguish the Two Types of Lung, Benign and Malignant Tumors

Not all lung tumors are cancer

Perhaps many people who when diagnosed with lung tumors immediately feel they have cancer. Although this is wrong, it’s understandable because most lung tumors are malignant. That is, most lung tumors do attack and kill the surrounding healthy tissue. In addition, this malignant lung tumor can metastasize or spread to other parts of the body or organs.

The lungs themselves become a dangerous place if already afflicted with cancer. This is because the lungs have a lot of tissue, including blood vessel tissue and lymphatic channels. Both of these tissues can be a medium for the spread of cancer cells throughout the body.

In some cases, lung tumors are the result of the spread of cancer cells originating from other parts of the body. The lungs themselves are a common location that is targeted for metastases of cancer cells from the entire body. If a lung tumor originates from cancer cells in other parts of the body, then the condition is not called lung cancer.

Types of Malignant Lung Tumors

Types of lung tumors that are malignant or cancer, are divided into two categories based on the type and location of the cancer cells begin to grow.

  • Non-small-cell lung cancer (NSCLC)

  • This type of lung cancer is cancer that usually originates from glandular cells on the outside of the lungs. The most common type of lung cancer NSCLC is adenocarcinoma. Non-small cell lung cancer can also originate from thin flat cells called squamous cells, called lung squamous cell carcinoma or epidermoid carcinoma. The most rare type of non-small cell lung cancer is large cell carcinoma. Cancers that are included in this type include sarcoma and sacchromoid.

  • Small-cell lung cancer (SCLC)

  • The cells lining the bronchi in the center of the lungs are a common source of small cell lung cancer. The main types of lung cancer in this group are small cell carcinoma and combination small cell carcinoma. The latter type is called a combination because it usually involves squamous cells or glandular cells. Small cell lung cancer (SCLC) is almost entirely caused by smoking and usually spreads faster than non-small cell lung cancer (NSCLC).

Some Types of Benign Lung Tumors

Lung tumors are not always malignant, because benign ones can also grow. Besides not spreading to other parts of the body, benign lung tumors also usually do not endanger the lives of sufferers. Some lung tumors below are categorized as benign tumors, namely:

  • Hamartoma

  • Hamartoma is an overgrowth of cells that look like cartilage. This is the most common type of benign lung tumor. Although slowly the size will enlarge, but this condition usually does not cause symptoms.

  • Papilloma

  • Papilloma is a benign lung tumor that grows out of the surface of the tissue. Benign tumors of squamous cells are the most common type of pulmonary papilloma. Papillomas tend to grow in the bronchi. Symptoms will appear if the growth of this benign lung tumor is blocking the airway.

  • Adenoma

  • Adenomas are benign tumors originating from cells in the gland that release mucous substances, hormones, or lubricating fluids. If they grow in the lungs, they are usually named according to the type of cells they form, such as alveolar adenomas and pleomorphic adenomas. This type of benign lung tumor is very rarely found.

Some benign lung tumors can be found from various tissues in the lung. Some examples of benign lung tumors are fibromas originating from connective tissue in the lungs, and lipomas originating from fat tissue. If a benign tumor is formed from smooth muscle cells, the designation for it is leiomyoma.

Symptoms of benign lung tumors are sometimes non-specific and are often similar to other diseases that also attack the respiratory system. Signs and symptoms of shortness of breath, wheezing, coughing up blood, chest pain when breathing deeply. Some types of lung tumors can secrete hormone-like substances that can cause symptoms outside the respiratory tract. The symptoms of this disorder resemble Cushing’s disease. Therefore, do a medical examination to the doctor even more if there are symptoms that lead to lung tumors.

Lung tumors, both benign and malignant, both must be aware of. The function of the lungs is vital for breathing. Thus, the lungs should be protected from various kinds of disorders, namely by stopping smoking and avoiding pollution. Living healthy habits with a healthy diet and regular exercise can also reduce the risk of lung cancer.
