Lung cancer types

Lung cancer types: Bronchogenic carcinomas

Lung cancer types

Lung cancer types are many and does not discriminate on gender

Lung cancers, are also referred to as bronchogenic carcinomas. Take note that carcinoma is another term for cancer. Lung cancer are broadly classified into two types as we had mention in our introduction blog. The classification include small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC). This classification is based upon the microscopic appearance of the tumor cells. These two kinds of lung cancer types can grow, spread, and are treated in different ways, so a distinction between these two types is important.

Lung cancer types: Small cell lung cancer (SCLC)

SCLC contains about 10%-15% of lung cancers. It is the most aggressive and rapidly growing of all types of cancers. It’s majorly caused by cigarette smoking. SCLCs metastasize rapidly to other parts of the body. And since symptoms doesn’t show early, by the time it’s discovered the cancer has spread extensively.

Lung cancer types: Non- small cell lung cancer (NSCLC)

This is very common, accounting for about 85% of all cases. It has three main types designated by the type of cells found in the tumor.

  • Adenocarcinomas are the most common type of NSCLC globally. Even though adenocarcinomas are associated with smoking like other lung cancers, this type is also seen in non-smokers especially women. Most adenocarcinomas arise in the outer, or peripheral, areas of the lungs. They also have a tendency to spread to the lymph nodes and beyond. People with this type of lung cancer tend to have a better prognosis than those with other types of lung cancer.
  • Squamous cell carcinomas were formerly more common than adenocarcinomas; today, they account for about 25% to 30% of all lung cancer cases. Also known as epidermoid carcinomas, squamous cell cancers arise most frequently in the central chest area in the bronchi. This type of lung cancer most often stays within the lung, spreads to lymph nodes, and grows quite large, forming a cavity.
  • Large cell carcinomas, sometimes referred to as undifferentiated carcinomas, are the least common type of NSCLC. This type of cancer has a high tendency to spread to the lymph nodes and distant sites.

Lung cancer types: Other types of cancers

These types are much less common than NSCLC and SCLC and together comprise only 5%-10% of lung cancers:

  • Bronchial carcinoids tumors are generally small (3-4 cm or less) when diagnosed and occur most commonly in persons under age 40. Unrelated to cigarette smoking, carcinoid tumors can metastasize, and a small proportion of these tumors secrete hormone-like substances. Carcinoids generally grow and spread more slowly than bronchogenic cancers, and many are detected early enough to be surgically removed.
  • Cancers of supporting lung tissue such as smooth muscle, blood vessels, or cells involved in the immune response are rare in the lung.

As discussed previously, metastatic cancers from other primary tumors in the body are often found in the lung. Tumors from anywhere in the body may spread to the lungs either through the bloodstream, through the lymphatic system, or directly from nearby organs. Metastatic tumors are most often multiple, scattered throughout the lung and concentrated in the outer areas rather than central areas of the organ.

Lung cancer symptoms

Lung cancer symptoms: What you need to know 

Lung cancer symptoms

Lung cancer symptoms when noticed need urgent attention

Lung cancer symptoms are not very common at the very beginning of cancer formation. It therefore, means that when signs and symptoms begins to manifest, chances are that the disease in progressively growing or advancing to more disturbing stages. It is ironical that while many are struggling with the disease today, it is something that can easily be prevented. Just by keeping distance to cigarette smoking is a step in the right direction. And remember that, to be safe, you must also avoid inhaling the second hand smoke from smokers. This is very important and as doctor Dalal Akoury MD, President and founder of AWAREmed health and wellness resource center puts it, when finally the signs and symptoms of the disease start to appear, they will be many include:

  • Worsening shortness of breath
  • Wheezing
  • Trouble swallowing
  • Swelling of the neck and face
  • Sudden changes in a cough that you’ve had for a long time
  • Respiratory infections that keep coming back, including bronchitis or pneumonia
  • Pain and weakness in the shoulder, arm, or hand
  • Hoarseness
  • Fatigue, weakness, loss of weight and appetite, fever that comes and goes, severe headaches, and body pain
  • Endless chest pain
  • Continuing, hacking, raspy coughing, sometimes with mucus stained with spots of blood

These problems usually happen because of blocked breathing passages or because the cancer has spread farther into the lung, nearby areas, or other parts of the body. When we allude to the fact that prevention is better than cure, it needs to be taken seriously. Therefore, when you notice any of the listed signs and symptoms above, timely action must be taken. Remember that these could be an indication of the lung disease. Having mentioned that these signs will most like come later in the development of the problem, when signs like an ongoing cough, blood-streaked mucus, wheezing, hoarseness, or a lung infection that keeps coming back appears, seek medical attention immediately. The doctor will run several tests including an X- ray to determine whether it is lung cancer forming. And when confirmed, treatment will start immediately.

Lung cancer symptoms: How common is lung cancer?

Studies have suggested that lung cancer is responsible for the most cancer-related deaths for both men and women across the globe. According to the American Cancer Society, they’ve estimated that 228,190 new cases of lung cancer in the U.S. were diagnosed and 159,480 deaths due to lung cancer occurred in 2013 alone. They have also established that lung cancer was not as common before in the 1930s, but has increased dramatically over time following decades of tobacco smoking increased. In many developing countries, the incidence of lung cancer is beginning to fall because of education about the dangers of cigarette smoking and effective smoking cessation programs. Nevertheless, lung cancer remains the most common form of cancer in men worldwide and the fifth most common form of cancer in women the finding states.

Lung cancer has surpassed breast cancer in causing the most cancer-related deaths in women in the United States. It means that the sooner we pool together in fighting this the better for all of us. You can call us today at AWAREmed health center for all your concerns and will address them professionally.

Lung cancer formation

Lung cancer formation: Types of lung cancer

Lung cancer formation

Lung cancer formation. When a member of the family is affected, the whole family is too and a collective support is necessary

It is believed that lung cancer formation starts right in the lungs and then spreads to other parts of the body. This disease starts in the walls of the lungs airways scientifically known as bronchi or bronchioles or in the air sacs known as alveoli. Once present, the lung cancer stages advances to other body parts. A patient can identify lung cancer from certain symptoms like shortness of breath, coughing, bloody mucus and wheezing. This disease can be treated using surgery, chemotherapy and radiation. With the help of experts from AWAREmed health and wellness resource center, we will be discussing these progressively. In the meantime, we have over 20 types of lung cancers with the two major ones being non-small cell lung cancer and small-cell lung cancer.

Lung cancer formation: Non-small cell lung cancer

Adenocarcinoma is the most common kind of non-small cell lung cancer with up to 40% cases. It affects mostly smokers or those who had quitted smoking. It also top the list of among non-smokers. Women are more vulnerable to this cancer than men. It can spread rapidly to the lymph nodes, bones, or other organs like the liver.

Squamous cell carcinoma. This often starts in the lung’s largest branches, also known as central bronchi. It accounts for about 30% of all lung cancer cases with men being more vulnerable besides smokers. It may form a cavity within the tumor and can cause the patient to cough up some blood. Squamous cell carcinoma can also spread to the lymph nodes, bones, and other organs such as the liver.

Large-cell carcinomas are a group of cancers with large cells that tend to start along the lungs’ outer edges. They’re fewer than adenocarcinoma or squamous cell carcinoma, making up 10%-15% of lung cancers. This type of tumor can grow faster and often spreads to nearby lymph nodes and distant parts of the body.

Lung cancer formation: Small cell lung cancer

This is the most destructive form of lung cancer. It begins from the lungs’ large, central bronchi. It affects mostly the smokers and spreads rapidly to other parts of the body like the liver, brain and bones even before showing symptoms. Secondhand tobacco smoke is also a cause. People who live with someone who smokes are 20% to 30% more likely to get lung cancer than those who live in a smoke-free home.

Finally, some other chemicals are risky too. Like for instance, people who work with asbestos or are exposed to uranium dust or the radioactive gas radon are more likely to get lung cancer, especially if they are smoking cigarette. Lung tissue that was scarred by a disease or infection like tuberculosis or scleroderma, becomes at risk for tumors in that tissue. Hypothetically, some researchers think that diet may also influence your risk. But that’s not clear yet.

Lung cancer risk factors

Lung cancer risk

Lung cancer risk factors are not far away from you. They include some of the substance you love most

Lung cancer risk factors: When life is threatened by cancer’s sting

I know that at the mere mention of the name cancer when the doctor is examining your health, you are likely to frown even if the doctor was not referring to your case. This is because cancer is a disease that scares everyone including people who may have an idea of what the lung cancer risk factors are. Take for example when a member of the family is down with cancer everybody is the concern. Many will wonder that if cancer is in the family and it is hereditary who is going to be the next victim or casualty? These concerns are justified and therefore it is only important that we do all we can to reduce the risk factors as much as we can. What can be avoided should and must be avoided so that we do not find ourselves in this state of panic. A risk factor for lung cancer is anything capable of increasing one’s chances of getting lung cancer. It is important at the onset to understand that having one or more of the risk factors is not a conclusion that one is definitely going to contract lung cancer it is not always the case. There are just indications of risks and not finality, as a matter of fact, one may portray a number of these factors but is still free from cancer while one who did not have any of the risk factors end up being diagnosed with lung cancer. I am put a lot of emphasis on this so that you are not scared in any way.

Lung cancer risk factors: Smoking

In order to understand this better, we spoke to doctor Dalal Akoury MD a veteran addiction expert for over two decades now and also the founder of AWAREmed health and wellness resource center. And in her evaluation cigarette smoking is one of the major risk factors for lung cancer even though it is not automatic that if you are smoking you will definitely get lung cancer, not at all, it only means that you have higher risk but not definite. Back to the discussion, as a risk factor it is estimated that out of a total of 100, 85 lung cancers are directly related to cigarette smoking be it cigars or pipe smoking all increases one’s risk for lung cancer. Smokers must be educated about the dangers of smoking because their risk of getting lung cancer increases depending on the quantity and the duration of smoking.

Quitting smoking lowers your risk for getting cancer. The good news about all this is that your risk will go down even if you partially stop, like if you are used to smoking one packet of 40 sticks of cigarette daily and you reduce it by half this reduction will go a long way in reducing your risk of getting lung cancer. Even though there will be reduction even on partial quitting it will be much better if you quit completely. That is why we want to encourage you to always seek professional help from doctor Akoury from time to time. Remember that these risks are all inclusive of the secondhand smokers. So waste not time and schedule for that appointment now.

Lung cancer health problems can be avoided if only you can avoid some of these drugs

Lung cancer health problems: Understanding the risk factors

It is true that cigarette smoking is a major factor when it comes to the understanding of what lung cancer health problems are, but it is worth noting that, it’s not all about cigarette smoking that increases the risk factors for lung cancers. Experts at AWAREmed health and wellness resource center under the leadership of doctor Dalal Akoury reiterates that there are other risks as well including:

  • Marijuana – This is a very powerful substance whose effect is very significant. Smoking just one marijuana cigarette, or a joint has the capability of affecting the lungs to the tune of smoking a whole pack of cigarettes.
  • Certain chemicals – These include arsenic and asbestos they are equally able to increase the risk.
  • Radiation – This comes a result of exposures from your workplace, medical tests, or from the environment (such as radioactive dust).
  • Radon gas – This includes exposure from your home or workplace.
  • Air pollution – Living where the air is polluted can increase your risk of lung cancer due to the inhalation of contaminated oxygen.

Lung cancer health problems: Changes in gene mutations

The risk of lung cancer may also come due to changes in gene mutations. These gene changes often occur as one approach old age. As the precautionary measure, it is important to seek medical attention immediately if you:

  • Experience unexpected onset of chest pain which is characterized by crushing or squeezing and is progressing in intensity, or appears with symptoms associated with heart attacks like shortness of breath and nausea.
  • Experiencing sudden difficulty in breathing.
  • If you are coughing up a lot of blood (not just streaks of blood or a small amount of blood mixed with a lot of mucus) from your lungs.
  • Have been vomiting and feeling that you are likely to pass out when you sit up or stand for some time.

As mention earlier cancer is a very devastating illness and it will be advisable that you are always in constant touch with your doctor to find out when an evaluation is needed resulting from your health experiences like if you:

  • Have new chest pain (more than just discomfort when you a cough) that lasts a long time and deteriorate when you take a deep breath.
  • Develop symptoms of pneumonia like shortness of breath, cough, and fever.
  • Have a cough that produces a small amount of bloody (bright red or rust-colored) mucus.
  • Frequently cough up yellow or green mucus from your lungs (not postnasal drainage) for longer than 2 days.
  • Vomit regularly when coughing.
  • Have a prolonged cough that goes for four weeks or even more.
  • When you breathe normally when you resting but lacks breathe after undertaking a physical activity.
  • Experience increasing fatigue for no good reason.
  • Have suddenly begun losing weight.

Finally, treating cancer very costly than preventing it. We have discussed some of the risk factors involved with smoking being the key in relation to lung cancer. We have a duty to defend health from the frustration of lung cancer by ensuring that what we can prevent is prevented. Drug addictions of any kind must be treated soonest and to do this involving expert at AWAREmed Health and Wellness Resource Center should be your starting point. If you are struggling with tobacco addiction, schedule an appointment with doctor Akoury today for the commencement of your recovery process professionally.
