First off, only TWO of your cites even contain the word "Cancer" in the title; and of those two, one (Marijuana Use and Cancer Incidence) states clearly in it's abstract that there IS NO RELATIONSHIP between Marijuana use and Cancer.
And while trying to find a non-paywalls version of the other study you cited that seemed reasonably on-point ((paraphrasing the title, because mobile slashdot ate my first attempt) "Marijuana and Cancer: Harmful or Helpful?"), I never did find that study thI could read without paying; but, along the way, I ran into this WONDERFUL study on an NIH site that I DARE you to reasonably and factually Rebut:

From the Cancer portion of that 42-page study/report:
Cannabinoids and Cancer
Possibly the greatest harm-reducing potential afforded by cannabinoids comes from their use by cancer patients. Cannabinoids possess numerous pharmacological properties that are often beneficial to cancer patients. Many people are aware of the anti-emetic and appetite stimulating effects of cannabinoids [64]. A systemic study designed to quantify the efficacy of cannabinoids as an anti-emetic agent examined data from 30 randomized controlled studies that were published between 1975 and 1997 and included 1366 patients who were administered non-smoked cannabis [65]. For patients requiring a medium level of control, cannabinoids were the preferred treatment (between 38% and 90%). This preference was lost for patients requiring a low or a high level of control. Sedation and euphoria were noted as beneficial side effects, whereas dizziness, dysphoria, hallucinations, and arterial hypotension were identified as harmful side effects.
The cancer cell killing [66] and pain relieving properties of cannabinoids are less well known to the general public. Cannabinoids may prove to be useful chemotherapeutic agents [67]. Numerous cancer types are killed in cell cultures and in animals by cannabinoids. For example, cannabinoids kill the cancer cells of various lymphoblastic malignancies such as leukemia and lymphoma [68], skin cancer [69], glioma [70], breast and prostate cancer [71], pheochromocytoma [72], thyroid cancer [73], and colorectal cancer[74]. Since 2002 THC has been used in a clinical trial in Spain for the treatment of glioma [75]. However, not all cancers are the same, and cannabinoid-induced biochemical modifications, while effective in killing the cells of some cancers, as indicated above, can have the opposite effect on the cells of other types of cancer. For example, recent work has shown that the synthetic cannabinoid, methanandamide, can promote the growth of lung cancer cells by a receptor independent pathway that involves the up-regulation of COX2 [76]. Although much has been learned about the therapeutic value of cannabinoid agonists and antagonists in different situations, scientific understanding of how to appropriately modulate the endocannabinoid pathways remains preliminary, with much remaining to be learned.
The rest of the report is equally enlightening (and enlightened), and I double-dog dare you to read it objectively and not come to the conclusion that you've been misled by all the fervent anti-Marijuana propaganda.
But, I feel I may be giving you too much credit. Feel free to prove that my opinion of you is incorrect, and that you can let facts "in", at least once in awhile, even when it means you have to reconsider something you have simply "decided" is true.
