Cancer is one of the worst and most common diseases; it affects
nearly 1 in 3 people at some stage in their life. It is well known that
food is one of the most common causes for this terrible disease, so the
better way to prevent it or fight it is by having a balanced diet and
lifestyle.

The available options leave you feeling incredibly ill and disable you
for months, or even years, this is the main reason why so many cancer
patients are turning to alternative medicine to help cure them of the
disease.
Nature is full of natural treatments for many illnesses, in this
specific case (cancer) soursop has been found to be 10,000 times
stronger than chemotherapy at attacking and killing cancer, but of
course pharmaceutical companies do not want you to know this since they
cannot patent natural chemicals.
These companies are trying to re-create the chemical structure in order
to make synthetic acetogenin that can be patented and marketed to its
full potential, one reason why they don’t support publically this
plant’s miraculous effects against disease and illness.
Nature is the cure, we are aware that this plant is powerful, you don’t
need a drug made from the plant, all you need is the delicious plant
itself. Fight diseases hand in hand with nature.
For those who say there is not any “credible scientific research” on
this fruit: Do you know how much a “credible scientific evidence” costs?
Probably tens of millions of dollars, and who might pay for that? NIH?
NSF? Pharmaceutical companies? Pharmaceuticals lobby against anything
that damages their profit, and NIH and NSF don’t care about “natural
alternatives”. The profits that each individual patient brings for
pharmaceutical industry is more than a million dollars and they never
want to lose that profit. So there might never be a “credible scientific
research” for this fruit or any other natural remedies in near future!
Here are couple of peer-reviewed articles that suggest strong
anti-cancer properties of soursop for patients with different forms of
cancer such as pancreatic cancer and a form of skin cancer:

#1: Those of you who know someone with pancreatic
cancer know this is one of the worst forms of cancer with a high
morbidity. I personally have lost a family member to it and this cancer
goes so rapidly that you can’t even imagine! Now this study, performed
both in-vivo and in-vitro, shows that the active agents in soursop
inhibit the generation of pancreatic tumors and their metastasis which
may lead to generation of new drugs:

Abstract
Pancreatic tumors are resistant to conventional chemotherapies. The
present study was aimed at evaluating the potential of a novel
plant-derived product as a therapeutic agent for pancreatic cancer (PC).
The effects of an extract from the tropical tree Annona Muricata,
commonly known as Graviola, was evaluated for cytotoxicity, cell
metabolism, cancer-associated protein/gene expression, tumorigenicity,
and metastatic properties of PC cells. Our experiments revealed that
Graviola induced necrosis of PC cells by inhibiting cellular metabolism.
The expression of molecules related to hypoxia and glycolysis in PC
cells (i.e. HIF-1α, NF-κB, GLUT1, GLUT4, HKII, and LDHA) were
downregulated in the presence of the extract. In vitro functional assays
further confirmed the inhibition of tumorigenic properties of PC cells.
Overall, the compounds that are naturally present in a Graviola extract
inhibited multiple signaling pathways that regulate metabolism, cell
cycle, survival, and metastatic properties in PC cells. Collectively,
alterations in these parameters led to a decrease in tumorigenicity and
metastasis of orthotopically implanted pancreatic tumors, indicating
promising characteristics of the natural product against this lethal
disease.

#2- Another study focuses on the benefits of soursop
in skin cancer in-vivo (live animals). Many previous studies suggest
the promising benefits of soursop in killing cancer in vitro (live cells
in test tubes), but this study shows the benefits on live mice:

Abstract
Annona muricata L (Annonaceae), commonly known as soursop has a
long, rich history in herbal medicine with a lengthy recorded indigenous
use. It had also been found to be a promising new anti-tumor agent in
numerous in vitro studies. The present investigation concerns
chemopreventive effects in a two-stage model of skin papillomagenesis.
Chemopreventive effects of an ethanolic extract of A. muricata leaves
(AMLE) was evaluated in 6-7 week old ICR mice given a single topical
application of 7,12-dimethylbenza(α)anthracene (DMBA 100 μg/100 μl
acetone) and promotion by repeated application of croton oil (1% in
acetone/ twice a week) for 10 weeks. Morphological tumor incidence,
burden and volume were measured, with histological evaluation of skin
tissue. Topical application of AMLE at 30, 100 and 300 mg/kg
significantly reduced DMBA/croton oil induced mice skin papillomagenesis
in (i) peri-initiation protocol (AMLE from 7 days prior to 7 days after
DMBA), (ii) promotion protocol (AMLE 30 minutes after croton oil), or
(iii) both peri-initiation and promotion protocol (AMLE 7 days prior to 7
day after DMBA and AMLE 30 minutes after croton oil throughout the
experimental period), in a dose dependent manner (p<0.05) as compared
to carcinogen-treated control. Furthermore, the average latent period
was significantly increased in the AMLE-treated group. Interestingly, At
100 and 300 mg/ kg, AMLE completely inhibited the tumor development in
all stages. Histopathological study revealed that tumor growth from the
AMLE-treated groups showed only slight hyperplasia and absence of
keratin pearls and rete ridges. The results, thus suggest that the
A.muricata leaves extract was able to suppress tumor initiation as well
as tumor promotion even at lower dosage.

Abstract
The cell inhibition activities of several Annonaceous
acetogenins, covering the three major structural classes of
bis-adjacent, bis-non-adjacent, and single tetrahydrofuran (THF) ring
compounds and their respective ketolactone rearrangement products, were
tested in an in vitro disk diffusion assay against three murine (P388,
PO3, and M17/Adr) and two human (H8 and H125) cancerous cell lines as
well as a non-cancerous immortalized rat GI epithelial cell line (I18).
The results demonstrate a dose-dependent inhibition of cancerous cell
growth, while non-cancerous cell growth is not inhibited by the same
dosages. All of the acetogenins, irrespective of their various
structural types, inhibit the growth of adriamycin resistant tumor cells
and non-resistant tumor cells at the same levels of potency. These
results show that the Annonaceous acetogenins are an extremely potent
class of compounds, and their inhibition of cell growth can be selective
for cancerous cells and also effective for drug resistant cancer cells,
while exhibiting only minimal toxicity to ‘normal’ non-cancerous cells.

#4- Another article here suggests that the
alcohol-based extract of the soursop leaves has strong anti-inflammatory
benefits and also reduces the pain. As you know many forms of skin
cancer cause a lot of pain in the patients. So this study might open the
door for production of new natural based drugs for people who suffer
from those pains. Here is more information:

Abstract
Antinociceptive and anti-inflammatory activities of the
ethanol extract from Annona muricata L. leaves were investigated in
animal models. The extract delivered per oral route (p.o.) reduced the
number of abdominal contortions by 14.42% (at a dose of 200 mg/kg) and
41.41% (400 mg/kg). Doses of 200 and 400 mg/kg (p.o) inhibited both
phases of the time paw licking: first phase (23.67% and 45.02%) and the
second phase (30.09% and 50.02%), respectively. The extract (p.o.)
increased the reaction time on a hot plate at doses of 200 (30.77% and
37.04%) and 400 mg/kg (82.61% and 96.30%) after 60 and 90 minutes of
treatment, respectively. The paw edema was reduced by the ethanol
extract (p.o.) at doses of 200 (23.16% and 29.33%) and 400 mg/kg (29.50%
and 37.33%) after 3 to 4 h of application of carrageenan, respectively.
Doses of 200 and 400 mg/kg (p.o.), administered 4 h before the
carrageenan injection, reduced the exudate volume (29.25 and 45.74%) and
leukocyte migration (18.19 and 27.95%) significantly. These results
suggest that A. muricata can be an active source of substances with
antinociceptive and anti-inflammatory activities.

#5- Although this study is performed on Annonacin,
extracted from apple custard, this compound is also found in Soursop.
This research also suggests strong anticancer properties of this
compound in various cell lines.

Abstract
Annonaceous acetogenins are a group of potential anti-neoplastic
agents isolated from Annonaceae plants. In this study, we purified
annonacin, a cytotoxic mono-tetrahydrofuran acetogenin, from the seeds
of Annona reticulata and analyzed its biological effects. Herein, we
have shown that annonacin caused significant cell death in various
cancer cell lines. T24 bladder cancer cells at the S phase were more
vulnerable to the cytotoxicity of annonacin. Furthermore, annonacin
activated p21 in a p53-independent manner and arrested T24 cells at the
G1 phase. It also induced Bax expression, enhanced caspase-3 activity,
and caused apoptotic cell death in T24 cells. In summary, these results
suggest that annonacin is potentially a promising anti-cancer compound.
