Lung Cancer is one of the most common cancers in the world; Research Essay [2]
Your grammar is not so bad. I am happy to offer sample edits and to give you guidance on editing your own essay. First I will tell you the kinds of errors you are making most frequently and how to fix them. Then I will offer some additional suggested corrections.
I notice that you commit the punctuation error known as the comma splice quite frequently. Here are some examples:
Lung cancer is formed when the cells of the lungs grow in an uncontrolled way, this creates a lump or a tumour which can either be malignant (cancerous) or benign (not cancerous).
Surgeries can remove tumours, radiation therapy kills cancer cells that cannot be removed by surgery
Very specific statistics were found, professional research was done for this article.
The article was written by two MDs, the wording is very professional, the effects on readers will be greater as well; the impact of their words is strong.
multiple comma splices in one sentence hereThis article was written by a non profit research organization, the article deals with the importance of healthy diets and the cure of cancer.
There are many more! In each instance, you have used a comma to splice together two phrases that could be complete sentences on their own. Instead of a comma, you should join the phrases with a semi-colon or separate them with a period.
This links to the primary problem with your writing in this piece: You try to do too much in each sentence. Sometimes you do correctly use semi-colons, rather than commas, to join two or more main clauses together into a single sentence. At other times, you mix commas and semi-colons as in the last example above. Either way, your sentences read awkwardly, because you are trying to fit too much information into each sentence.
There's no need to do that! Look at this sentence, which has two comma splices:
Cigarettes are full of poison and toxic chemicals, the ingredients affect everything from functions of organs to body's immune system, the damages can be widespread and fatal.
You could correct the punctuation by changing the commas to semi-colons, but why? Why put all of that into a single sentence? Why not make it three short, simple, clear sentences? Or, at minimum, break the first clause off into its own sentence and then join the other two with a semi-colon, since they are closely related.
In general, the only time to combine clauses that could stand as their own sentences into a single sentence is when they are part of a single thought.
Here are a few additional specific suggestions:
Terry,T he author of this article did a lot of research on cigarette and the chemicals used to make it
