Non-small cell lung cancer (NSCLC):

About 80% to 85% of lung cancers are NSCLC. The three major subtypes include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. These subtypes start in different cell types within the lung but are treated as the same cancer type due to similarities in the treatments and outcomes.

Small cell lung cancer (SCLC):

It represents 10% to 15% of all lung cancers. It grows and spreads quicker than NSCLC. In most patients, it has spread beyond the lungs at the time of diagnosis. SCLC responds well in most cases to chemotherapy and radiation, however, it tends to recur.

Other types of lung tumors:

Carcinoid lung cancers make up less than 5% of lung cancers and tend to grow rather slowly. In addition, adenoid cystic carcinomas, lymphomas, and sarcomas are some of the other rare lung cancers that present in rather different ways from those previously mentioned.
Secondary cancers or metastatic cancers are those originating from another organ, like the breast or kidneys that can metastasize to the lungs but are still classified based on the organ where they first began. For example, metastasized breast cancer to the lungs remains classified as breast cancer and not lung cancer. Treatment of the metastatic cancer depends on the source of the metastasis.
Lung cancer directly affects your breathing system. It can be deadly if you do not notice it at an early age. But, if you are from Lucknow then no need to be worried about it. For Lung cancer treatment in Lucknow, Dr. Amit Panday is a well-known oncologist in Lucknow. You can consult him for medical treatment of lung cancer.

Symptoms of Lung Cancer:

Lung cancer is not usually symptomatic. Many of the symptoms associated with this disease can feature in other diseases. Sometimes early detection can make the treatment a bit easier. So, it is important to see your GP if you notice or feel any sign or change.

Common Symptoms of Lung Cancer:

New or Continuing Cough: A new cough or a cough that persists over time. Shortness of Breath: Shortness of breath while undertaking tasks that he could formerly accomplish with ease. Hemoptysis: Coughing up blood-stained sputum Chest or Shoulder Pain: Insistent ache or pain in the chest or shoulder. Recurrent Chest Infections: Repetitive or persistent chest infection without improvement. Loss of Appetite: Poor interest in eating. Fatigue: Feeling tired all the time. Weight Loss: Unexplained or unintentional loss of weight. Lung Changes on X-rays: Sometimes, abnormalities may appear on a chest x-ray, which was done for some other purpose. These abnormalities do not suggest that there is lung cancer; most of them are due to an infection. Further studies are sometimes needed to answer the question.

Finger and Fingernail Changes:

Finger Clubbing: Swollen fingers and nails. More commonly seen in patients with non-small cell lung cancer. HPOA (Hypertrophic Pulmonary Osteoarthropathy): Joint pain and swelling. Hormone-Related Symptoms: In very rare cases, some lung cancer cells send hormones into the bloodstream and trigger symptoms not related to lung cancer. This is known as paraneoplastic syndrome and occurs much more frequently with small-cell lung cancer. There can be: Nausea and Vomiting Headaches Confusion or Trouble Thinking Clearly Weakness or Fatigue Restlessness or Irritability Muscle Weakness, Spasms, Cramps, or Aches Seizures or Fainting Problems walking, climbing stairs, or lifting things Drooping Eyelids, Dry Eyes, and Blurred Vision Dizziness when standing Dry Mouth Constipation Impotence Muscle Weakness That Worsens Over Time but Can Sometimes Be Improved by Activity

Pancoast Tumors: An extremely rare type of lung cancer, called a Pancoast tumor, occurs at the very top of the lung and causes special symptoms:
Severe Shoulder Pain: This can include pain that shoots down the arm or up the head and neck.

Horner's Syndrome: A symptom group that involves drooping or weakness of one eyelid, a small pupil in the same eye, and loss of sweating on one side of the face. These symptoms result from the pressure that the tumor has exerted on a nerve that runs from the neck down into the face.

Tests for Lung Cancer: Your GP or specialist may diagnose lung cancer using any of the following tests: Chest x-ray, CT scan, PET-CT scan, bronchoscopy, and biopsy.

Treatment of Lung Cancer

Treatment of lung cancer often depends on several issues, including the type, size, and stage of cancer, in addition to the health of the patient. A consensus is often reached by a team of doctors and other healthcare professionals concerning the most appropriate and optimal treatment and care plan. Dr. Amit pandey can be the best medical oncologist in Lucknow for anyone who is suffering from lung cancer or other types of cancer.

Prehabilitation: Small cell lung cancer treatment is determined by a healthcare team according to the stage of the cancer. Treatments can vary and will be determined based on a person's needs. Treatment of NSCLC: Treatment of non-small cell lung cancer will depend on a medical team. The treatment that may be undertaken will depend on the stage of the cancer and other personal factors. Radiotherapy: Radiotherapy is one of the most commonly performed procedures given for the treatment of lung cancer and often involves external radiotherapy in which radiotherapy from an appliance is focused directly at the cancer to destroy it. Chemotherapy: Chemotherapy is usually prescribed as a method of treatment for both small-cell and non-small-cell lung cancer. It consists of drugs with cytotoxins that kill the cancerous cells. Targeted and Immunotherapy: Metastasizing lung cancers can cause various symptoms as mentioned above and there are treatments to alleviate those symptoms so that the patient is made comfortable. Photodynamic Therapy (PDT): Photodynamic therapy involves a light-sensitizing drug combined with intense light to destroy cancer cells. This is among the treatments for lung cancer. Laser therapy of lung cancer: A laser is a very thin, extremely concentrated beam of light that is used to heat and destroy tissue. Lasers can focus very precisely on small areas. Thermal ablation for treatment of lung cancer by heat: Ablation means to kill or destroy. Doctors can use heat to destroy the new tumours that begin in the lung. Diathermy (electrocautery) for lung cancer: Diathermy therapy employs an electrical current to heat and destroy cancer cells. Ease your breathing for lung cancer treatments
Lung cancer may prevent air from getting into your lungs. If it does, some of your lung cancer treatments may help you breathe more easily. Lung cancer cryotherapy: Cryotherapy is a metastatic lung cancer treatment that freezes cancer cells to kill them. It can reduce the size of an obstructing tumor. Airway stent: open airway: A hollow tube called a stent can be inserted into your airway. It opens up the narrowed area and allows you to breathe. Follow-up after lung cancer treatment: When you have had lung cancer treatment, you regularly visit the hospital. You also undergo tests such as blood tests, x-rays, and scans.
