Lung Cancer

Lung Cancer Facts & Tips for Prevention

Lung cancer is one of the most common cancers in the world⁠.

In 2015, it was estimated that approximately 26,600 Canadians would be diagnosed with lung cancer.  That is more than any other type of cancer.

In addition to this, more people die from lung cancer than breast cancer, colorectal cancer and prostate cancer combined.

There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC)⁠.

Non-small cell lung cancer accounts for about 85 percent of lung cancers, small cell lung cancer about 15 percent.⁠

NSCLC usually starts in glandular cells on the outer part of the lung. This type of cancer is called adenocarcinoma. Non–small cell lung cancer can also start in flat, thin cells called squamous cells. These cells line the bronchi, which are the large airways that branch off from the windpipe (trachea) into the lungs. This type of cancer is called squamous cell carcinoma of the lung. Large cell carcinoma is another type of non–small cell lung cancer, but it is less common. There are also several rare types of non–small cell lung cancer. These include sarcoma and sarcomatoid carcinoma.  SCLC usually starts in cells that line the bronchi in the centre of the lungs. The main types of small cell lung cancer are small cell carcinoma and combined small cell carcinoma (mixed tumour with squamous or glandular cells).

Anatomy & Facts About Our Lungs



Did you know?

  • In proper anatomy our right lung is shorter and wider than our left.  Our left lung is narrower and more oblong
  • The anterior border of the left lung is marked by a deep cardiac notch while the right lung is straight
  • Our left lung is smaller than our right lung because our heart occupies space on the left side
  • Our right lung consists of 3 lobes.  Our left lung has 2
  • Our right lung connects to the trachea by two bronchi while the left lung connects to the trachea by a single bronchus

Possible causes of lung cancer

🔹Cigarette smoking causes most lung cancers.  Of note however many patients who are diagnosed with lung cancer have either never smoked or are former smokers.

🔹Exposure to high levels of pollution⁠

🔹Exposure to radiation and asbestos may increase risk of lung cancer⁠


Common symptoms of lung cancer

✔️A cough that doesn’t go away and gets worse over time⁠

✔️Constant chest pain⁠

✔️Coughing up blood⁠

✔️Shortness of breath⁠


Help lower your risk of lung cancer by incorporating the following tips

☑️Stop Smoking:⁠

Smoking is responsible for the majority of lung cancers. If you are a smoker it’s never too late to quit. For those who have been diagnosed with lung cancer, by stopping your smoking habit you can make cancer treatment more effective

☑️Limit Your Chemical Exposure:⁠

Chemicals in the workplace and at home can contribute to lung cancer

☑️Reduce Your Exposure to Second-Hand Smoke:⁠

Exposure to second-hand smoke increases your chance of developing lung cancer

☑️Consume Green Tea and Black Tea:⁠

Studies have shown that consuming Green & Black tea are associated with a reduced lung cancer risk⁠

As well as the above, proper sleep, exercising regularly and eating a diet rich in fruits and veggies are very important habits for cancer prevention as a whole.⁠



Common Signs That Your Liver May Need Some Attention

Weighing between 3.17 and 3.66 pounds (lb), or between 1.44 and 1.66 kilograms (kg), your liver is the largest solid organ in your body (mine too!) and performs over 500 functions including being a key detoxifier.

So your liver works hard every day.  But sometimes it gives us signs that it may need some support.

Here are some indications that you may need to give your liver some lovin’.

Do you wake up at night?

If you wake up consistently between 1:00am and 3:00am, your liver may be asking for some support. While we sleep, the liver becomes more active and works on cleansing and detoxification. Waking up around this “liver time” can signal that the liver is exhibiting signs of toxicity and needs some detoxing.  Many times this happens from eating either too much sugar in the evening or animal protein.


Eye problems

Conjunctivitis, lots of mucus, itching, macular degeneration, dry eyes, and cataracts may indicate liver weakness. Another physical clue is a vertical line between the eyebrows.



Angry emotions

If the liver is congested and being forced to work too hard, it becomes “hot,” causing excessive anger and irritation.

Hormonal imbalances

PMS, hot flashes, and pre-menopausal symptoms are increased due to a congested liver.

Skin Problems

Eczema, psoriasis, rosacea, skin rashes, acne and dry skin are clues.


This condition can often be caused by a congested and toxic liver or even stressed adrenals. The colon should still be addressed, but it is often not the root cause.

 10 Steps that Support a Healthy Liver

  1. Eliminate toxins from your diet and your life as best you can.
  2. Drink pure (filtered) water throughout the day.
  3. Drink your lemon water first thing every morning.
  4. Eat dark greens, preferably raw, every day (e.g. “green juice”, a big or green salad). Eat lots of celery (a good source of plant sodium that helps support the adrenals), watercress, broccoli, kale, cucumber, spinach, romaine, fresh herbs like basil and cilantro, and sour green apples.
  5. If not vegan or vegetarian, eat animal protein between 10 a.m. and 3 p.m. It can be stressful for the liver to eat the animal protein later in the day or evening, especially if you are showing signs of liver stress.
  6. Remember, you need protein to support and detoxify the liver. In addition to protein naturally found in meats, good complete protein sources can be found in beans, nuts and seeds such as hemp seeds and chia seeds.
  7. Eat dinner at least 3 hours before bedtime.
  8. Make sure the colon is supported and clean. When toxins remain in the colon, they are sent back to the liver. The liver then sends them right back down to the colon in the bile. To help permanently eliminate these toxins from the body, add extra fiber, probiotics, and filtered water.
  9. Sweat! Saunas and exercise are a good way to sweat.
  10. Assist your lymphatic system – Use a body brush every day to stimulate your lymphatic system and help move lymphatic fluids. You can also lymphasize, which is a way to stimulate lymphatic drainage, ridding your body of toxins, wastes, trapped protein, bacteria, and viruses.  What do you need to do?  Jump on a mini-trampoline — this is called rebounding.  This creates an ideal condition for cleaning the cells.  The vertical acceleration and deceleration help the cells squeeze out waste.
