Lung Cancer: What You Need to Know

4 mins

The shock began to dial down after a couple of hours. The next thing that was supposed to set in was regret, but how could he regret what he could not point out.

“I don’t smoke, I have never lit a cigar’ he mumbled continuously.

“I am just 52 years old; how can this be?” he soliloquized.

How could it be, was it his diet? Stress? What could have caused this? No amount of preparation could have prepared this construction worker for the diagnosis, what was worse? Mr. Dele (not his real name) had no idea on the next step to take.

Cancer is the growth of abnormal cells that can occur in any part of the body. Lung Cancer is a type of cancer that originates from the lungs.

According to the International Agency for Research on Cancer, there are 11.6% of recorded cases worldwide and 1.2% of recorded lung cancer cases in Nigeria. (Cancer, 2018)

Types of Lung Cancer

The two main types of Lung Cancer are;

  • Small Cell Lung Cancer (SLSC) also known as Oat Cell Cancer is the type of lung cancer in which the cancer cells originate from the lung tissues.  10-15% of Lung Cancer are SLSC. This type of Cancer tends to spread faster than the second type.
  • Non-Small Cell Lung Cancer (NSCLC) accounts for 80-85% of lung cancer cases.

Causes of Lung Cancer

When lung cancer is mentioned, the first cause to point out is smoking and rightly so. The first on the list is therefore;

  • Smoking- Cigarettes contain carcinogens, a substance that damages the cells lining the lungs. About 10-15% of smokers develop lung cancer. It is advisable not be entangled in the act of smoking because the aftermath can still rear up years after quitting. Quitting at an early age can however lower the risk. Cigarette smoking is not limited to causing cancer of the lungs, it also accounts for other types of cancers.
  • Secondary (passive) Smoking- You don’t need to be a smoker to be prone. Being in an environment where people smoke leaves you liable to lung cancer. Smoke from other people’s pipe or cigar puts you at the same risk as the person smoking.
  • Asbestos- Asbestos is a mineral that occurs in nature, it is used in the production of bricks, pipes, paints and flooring. This is why construction workers and miners are susceptible to lung cancer.
  • Exposure to Radon – The breakdown of Uranium in the soil, water and rock leads to the production of Radon. A good source of radon is the phosphate fertilizer. The radon gas in the atmosphere breaks down into tiny radioactive elements that can cling to the lining of the lungs and give off radiation.
  • Genetics- A history of lung cancer in the family tree is something to watch out for. Family history is a risk factor for Non-Small Cell Lung Cancer.

Symptoms of Lung Cancer

The symptoms of lung cancer vary with individual and with stages.

The common symptoms include;

  1. Coughing that gets worse or doesn’t go away.
  2. Chest pain.
  3. Shortness of breath.
  4. Wheezing.
  5. Coughing up blood.
  6. Feeling very tired all the time.
  7. Weight loss with no known cause.

Pneumonia and swollen lymph nodes can also occur as the cancer advances. 25% of people who suffer from the disease show no symptoms at all until it is discovered on the Chest X-ray or CT Scan. This is why it is advised to Consult a Doctor for check-up regularly.

Treatment of Lung Cancer

Lung Cancer is not a death sentence especially if detected early. The methods for treating Lung Cancer include

  1. Surgery– a medical procedure in which the cancerous tissue is cut out.
  2. Chemotherapy which involves using drugs to shrink or kill the cancer.
  3. Radiation therapy- also known as radiotherapy involves using high energy rays to kill the cancer
  4. Targeted therapy- involves using drugs to inhibit the growth of the cancerous cells.

Just like Mr. Dele, most patients are clueless as to how they ended up being a victim of lung cancer. Nonetheless, being diagnosed with lung cancer is not the end of the road.

Lung cancer can be prevented, managed and even conquered with the right lifestyle and approach. Living a healthy life and going for regular check-ups are fundamental steps towards keeping this enemy at bay.

Can’t still believe that i got cured from Genital Herpes through herbal treatment from Dr.Afrid who I met through the internet, I actually couldn’t believe it at first because it sounded impossible to me knowing how far I have gone just to get rid of it. Dr.Afrid send me his medicine which I took as instructed and here I am living a happy life once again, a big thanks to Dr.Afrid, I am sure there are many herbal doctors out there but Dr.Afrid did it for me, contact him , also call or whatsApp him on +2349057260738.

I still don’t know the right words to express my gratitude to this great man Dr. Agbomian. After been diagnosed of HERPES SIMPLEX VIRUS in 2months ago, i was given so many health prescription and advice with no improvement, I totally lost hope, until i found testimonies of Great Dr. Agbomian  online research and on Facebook, Like anybody would be, I was very skeptical about contacting him, but i later did and he opened up to me and told me what was involved and he started the remedies for my health. Thank God, i was cured from herpes by the herbal medication I received from him. I never thought that herpes can be cured from the bottom of my heart I’m truly grateful, i pray you have long life so you can help many more people on earth with your herbal medical support, You can Email him via email or for easy and fast communication you can also call or add him on whats-app with this mobile number +2347040843115, one thing i love most about DR  Agbomian    is honestly, and he is very polite with his patience, everything he told me was what he did, and his herbal medicine are very affordable.

Natural herbs have cured so many illness that drugs and injection cant
cure. I’ve seen the great importance of natural herbs and the wonderful
work they have done in people’s lives. i read people’s testimonies online
on how they were cured of herpes, HIV, diabetics etc by Dr. voodoo herbal
medicine, so i decided to contact the doctor because i know nature has the
power to heal anything. I was diagnosed with HIV for the past 7 years but
Dr. voodoo cured me with his herbs and i referred my aunt and her husband
to him immediately because they were both suffering from herpes but to God
be the glory, they were cured too .I know is hard to believe but am a
living testimony. There is no harm trying herbs. He is also a spell caster,
he cast spell to restore broken marriages and he cast good luck spells to
prosper and excel in life. Contact Dr voodoo on Whatsapp or call him
+2348140120719 OR email him

When my herpes started interfering with my daily life. And my lips always bother me every damn day. I remember going to the hospital when I was around 25 years old cuz my whole lips were burning like hell. And a nurse came to the waiting lobby and said sorry there are no doctors here. So I had to go back home. My lips were burning like hell and I felt so uncomfortable that night so I turned to the internet where I found Herbal Doctor Oduku Paul . I am 40 years old.This virus has been totally eliminated with their herbal system , My lips were messed up. They are okay when I apply chap-stick, but if I don’t apply chap stick they will get tight and dry and ashy and the skin will get burnt and hard. And they always feel tingly. The burning sensation stopped after that day I started their herbal cure. I don’t want to walk around with glossy lips. I’m a man. I don’t know what would have heal me from this virus if not for the product. I took a comprehensive STD blood test last week again and everything came out negative.,contact today Call Us or whatsapp +2349064430408 they have the right treatment to STD.
