7 Early Signs of Lung Cancer You Must Watch Out

Early diagnosis can help save lives.






Cancer is a dreaded disease. Just the mere mention of cancer in a doctor’s diagnosis is enough to give a patient a panic attack.

Cancer begins in the cells. Normally, cells are formed whenever necessary to replace the old cells that die. However, this process sometimes becomes disrupted – some cells form uncontrollably and some do not die when they should. This disruption results in the formation of a mass called a tumor. Tumors can either be benign or malignant. Benign tumors generally aren’t a significant cause of alarm. However, malignant tumors can invade other tissues in the body and cause severe disease.


According to MedLine Plus, there are more than 100 types of cancers, and most of them are named based on the anatomical site where they originate. One of the most common types of cancer is lung cancer. Symptoms commonly do not become apparent until the disease is at an advanced stage. Fortunately, there are seven warning signs that can help us detect lung cancer before it gets too late.

#1. Persistent Cough

Having a cough may mean that you have a respiratory infection that generally does not cause alarm. But having a cough that lasts for more than 2 weeks might mean that you need to visit your doctor and have relevant tests such as chest X-ray performed. This is particularly important if you have a persistent productive cough and is accompanied by other symptoms such as coughing up blood.

#2. Shortness of Breath

Shortness of breath is another symptom that develops in patients with lung cancer. It occurs as a result of several factors such as anemia, fluid in the lungs or in the abdomen, blockage of blood vessels, or tumor growth. If you notice that you have become increasingly out of breath after climbing a flight of stairs, and this doesn’t normally happen before, you might need to pay your doctor a visit.

#3. Chest, Back, or Shoulder Pain

Chest pain that becomes worse with deep breathing, laughing or coughing occurs in about 25% of patients with lung cancer, and the pain may radiate to the patient’s back or shoulders. But remember that chest, back, or shoulder pain are not always caused by cancer, so it is important to tell your doctor about these symptoms.

#4. Wheezing

A wheezing sound indicates the passage of air through narrowed airways. However, do not panic when you hear a wheezing sound during breathing as this can also indicate a much more benign condition such as asthma. But if it persists and becomes more prolonged, then go and pay your doctor a visit.

#5. Unexplained Weight Loss

Weight loss typically occurs in patients with cancer, and it is often among the first noticeable signs of the disease. Patients may lose weight due to loss of appetite, increased metabolic demand, and the side effects of treatment such as mouth sores and nausea and vomiting.

#6. Bone Pain

Bone pain develops if lung cancer has metastasized to the bones. Pain is usually felt in the backbone, ribs, and bones of the thigh and hips, and typically increases with activity. Again, consult your doctor if you experience this symptom.

#7. Headache

Headaches associated with lung cancer may occur as a result of metastasis to the brain. Headaches may also develop when the lung tumor compresses the blood vessels that carry blood to and from the brain. However, constant headaches may indicate a lot of things aside from cancer, so we urge you to not panic. It is still best to consult your doctor.

Again, we would like to emphasize that having one of these symptoms does not mean that you have lung cancer. But it may be prudent to you consult your doctor if you experience one of the abovementioned symptoms, especially if it begins to bother you or disrupt your activities of daily living.

Epic Battle for Survival Between a Shark and an Octopus

In a battle between two powerful, sea creatures, who do you think would win?

Ann Moises



Sharks are fierce, strong, and scary. The minute it bites its prey with its sharp teeth, you’ll know that there’s no escape and that you’ve seen the last of its victim. Sharks are at the top of the food chain, and no one doubts that.

Dogfish sharks are not considered dangerous; however, they do have sharp teeth that can seriously injure its prey. Also, the spines on their dorsal fins are slightly poisonous. Dogfish sharks otherwise called skittle dog, spotted dogfish, cod shark, white-spotted dogfish, thorndog, or piked dogfish, predominantly feed on fish, although they eat squid and octopus too.

In a huge aquarium where dogfish sharks and other sea creatures such as this giant, pacific octopus dwell, you’ll probably think that the sharks have plenty to prey on. However, the staff wondered why shark carcasses keep turning up, so they decided to set up cameras to solve the conundrum.
