Stage 4 Breast Cancer Treatment in Mexico: Maria's Patient Story

Maria Petulla, a patient from Brooklyn, New York, was diagnosed with stage 4 breast cancer that had spread to the bone. In this patient video she shares her experience with breast cancer treatment in Mexico at the Immunity Therapy Center (ITC) in Tijuana.

Speaking openly, Maria explains what led her to travel to Tijuana, what her care was like, and the changes she says she has seen since she arrived.

Maria's Story in Her Own Words

In this video, Maria Petulla looks back on what led her to ITC in Tijuana. She describes living with stage 4 breast cancer that had spread to the bone, losing the use of her left arm to lymphedema, and the day she decided she did not want things to get worse.

She then talks about her care at the center, the doctors and staff she met, what Tijuana was like during her stay, and the results she says she has seen. She finishes with a message for other patients who are unsure about making the trip.

Stage 4 Breast Cancer with Bone Metastasis

Stage 4 breast cancer means the cancer has spread beyond the breast to other parts of the body. In Maria's case it had spread to the bone, which is called bone metastasis.

Maria says her diagnosis was stage four breast cancer with metastasis to the bone [00:10]. She says she had tried to heal her cancer naturally on her own and could not. She had some symptoms she could see, and they were getting worse, so she came to ITC to stop it from moving forward.

She also says she had chosen not to do chemo, radiation, or therapy in the United States [00:40].

Lymphedema and Daily Life

Lymphedema is swelling that happens when lymph fluid does not drain properly, often because lymph nodes are blocked or damaged.

Maria says she started losing the ability to use her left arm. She had lymphedema in that arm because her lymph nodes became clogged, and she became partially disabled [00:45].

She says her voice is much better now but was much worse before, and that she had unbelievable pain from a wound on her left breast, which was also extremely debilitating. Her quality of life was getting very low. Then one day she woke up and felt the lymphedema in her face, as she had felt it in her arm [01:12].

Why She Chose ITC

At that moment, Maria says, she did not want to become even more disabled or let things get worse. She knew ITC could help her not only stop it from getting worse but also improve her condition [01:25].

ITC is the Immunity Therapy Center in Tijuana, Mexico. You can also read patient reviews of the center.

Her View of the Therapies

Asked about the therapies at ITC, Maria says everything is very easy there and that all of the therapies are very scientifically based. She says she is very impressed by that. She mentions the different machines, the IVs she receives, and the support, and says every single part of it is helping patients heal and building their immune system [01:38].

She found the experience extremely non-invasive, very safe, and very easy to just show up and get healed. These are her own impressions as a patient.

Dr. Bautista and the Staff

Maria says she had read Dr. Bautista's bio before meeting him. She describes him as a man who had seen his father suffer so much that he wanted to do anything he could to prevent other people from going through that [02:10].

She says she knew he had gone around the world to do research. When she met him, she felt he was coming straight from the heart, and she believed he had scientific proof that these modalities would work. She says she had no doubt he could help her and trusted him right away.

About the staff, she says everyone has a gentleness that she finds unmatched in the United States, one that looks at the whole person. She says being treated like a living being, as opposed to someone who is going to die, is a very different perspective. She also recalls a day when Dr. Alvarez shared how he deals with his own bad days, and she found it sweet and caring [03:12].

Life in Tijuana

Asked about Tijuana after being there for some time, Maria says it feels like an upper-class neighborhood and completely safe. To her it feels a lot like America, except speaking Spanish [03:48].

She mentions a lot of nice restaurants and nice shops, and says it does not feel unsafe in any way whatsoever [04:00].

Results She Reports

Tumor markers are substances in the blood that doctors can measure to help track a cancer. Maria reports the following results in her own words:

  • She says her cancer markers were over 3,000 when she first arrived, which she calls an astronomically high number and one of the highest Dr. Alvarez had ever seen [04:18]. She says the number dropped to 500 with the therapies at ITC.
  • She says she has never had pain in her bones, which she understands to be a big positive for bone metastasis [04:45].
  • She says her lymphedema went down more than 50%, her breast wound pain is gone completely, and the skin is starting to heal.
  • She says she used to be unable to bend over because of the pain, and can now touch her toes.
  • She says her breast had been attached to the chest wall by the cancer, and is now moving freely [05:12].

Her Message to Other Patients

Asked what she would say to people who hesitate to come to ITC, Maria says she believes these treatments work. She says that because a lot of science and research is not put behind them, it does not mean they cannot work. She adds that there are true stories of healing without long-term side effects [05:45].

She says the focus at ITC is building the immune system and building a body where the cancer cannot live, rather than only killing the cancer [06:20]. She closes by saying people should trust that there are results here, and that people are living long lives after coming to ITC.

[00:06]
My name is Maria Petulla. I'm from Brooklyn, New York, and my diagnosis was stage four breast cancer metastasis to the bone.

[00:15]
I had tried to heal my cancer naturally on my own, and I couldn't do it. And so, I had some symptoms that I could see and they were getting worse. So I came here to stop it from moving forward.

[00:28]
[Text on screen: How did this condition affect you in your daily life?]

[00:34]
Well, in my daily life, I started losing the ability to use my left arm. And I had chosen not to do any chemo, radiation, or therapy in the United States.

[00:43]
But I had lymphedema in my left arm because the lymph nodes became clogged. So I became partially disabled.

[00:51]
And my voice is much better now, but it was much worse. And I also had unbelievable pain because there was a wound on my left breast, and that was also extremely debilitating.

[01:05]
So I was starting to have a very low quality of life. And one day I woke up and I felt the lymphedema that I had felt in my arm, I felt it in my face.

[01:16]
And I said, that's it. I don't want to become even more disabled. I don't want this to get worse. And so I knew that ITC could help me not only stop it from getting worse but improving my condition.

[01:30]
[Text on screen: What do you think about the therapies here at Immunity Therapy Center?]

[01:37]
Everything is very easy here. It's very scientifically based, all of the therapies, and I'm very impressed by that. All of the different machines that we use, all the IVs that we receive, the support that we're getting. Every single part of it is helping us heal and building our immune system.

[01:56]
So I found it extremely non-invasive, very safe, and very easy to just show up and get healed.

[02:04]
[Text on screen: What do you think about Dr. Bautista and your thoughts upon meeting him?]

[02:10]
My first impression of Dr. Bautista was one of a man who had, because I had read his bio, a man who had seen his father suffer so much that he wanted to do anything he could to prevent other people from doing that.

[02:23]
And I know he had went around the world to do all this research. And so, when I met him, I knew he was coming straight from the heart, that he had scientific proof that these modalities would work.

[02:38]
And so I had no doubt that he would be able to help me. And I trusted him innately, right away.

[02:44]
[Text on screen: What do you think about the staff here at Immunity Therapy Center?]

[02:51]
Well, I find everyone here to have a gentleness that is unmatched in the United States. The gentleness really looks at the whole person. So being treated like a living being as opposed to someone who's going to die is a very different perspective.

[03:09]
Dr. Alvarez also helped me one day when I was just, you know there's good days and bad days. And one day he told me how he deals with his bad days, you know he deals with cancer patients all the time.

[03:20]
So for him to share some of his ways of dealing with the stress, or the up and down days of his own work, helped me as well. I thought it was just very sweet and very caring for him to share that it happens to everyone.

[03:41]
[Text on screen: What do you think about Tijuana, now that you have been here for some time?]

[03:48]
Tijuana feels like a somewhat of an upper-class neighborhood. It feels like it's completely safe. Feels a lot like America to me, except speaking Spanish.

[03:59]
And there's a lot of nice restaurants, a lot of nice shops. It doesn't feel unsafe in any way whatsoever.

[04:09]
[Text on screen: What are your results as of today?]

[04:15]
Well, when I was here first, my cancer markers were over 3,000, which is an astronomically high number, and one of the highest Dr. Alvarez had ever seen.

[04:29]
With the therapies here, my number dropped to 500. And that in and of itself is a miracle. Because still again in the United States they say you can't turn back stage 4 cancer.

[04:42]
I never have had any pain in my bones, which for bone metastasis is apparently a huge, huge positive.

[04:52]
My lymphedema went down more than 50%. My breast wound pain is gone completely, and the skin is starting to heal.

[05:01]
I used to not be able to bend over because of the pain, now I can touch my toes. So there's just so many changes that I've seen, not just with the cancer markers.

[05:11]
Also, my breast was attached to the chest wall, the cancer, and now my breast is moving freely. So it's not attached to the chest wall anymore. I mean, these are huge changes.

[05:22]
[Text on screen: What message do you have for people who are hesitant to come here to get treated?]

[05:29]
I think there's a lot of truth that hasn't been allowed to be out in the open. Which is these modalities work, these treatments work. And because a lot of science isn't put behind it, and a lot of research isn't invested in it, doesn't mean it's not a system that can't work.

[05:50]
It's a different way of looking at it, but it works. So just because it doesn't match the statistics in your country, or the statistics that you think it should match, and there's just more testimonials here or something like that, there are true stories of actual healing without side effects.

[06:06]
Without long-term side effects. So you don't have to suffer, live a life that's half-lived after really intense 100% chemo or treatments that are going to hurt your body and your immune system.

[06:20]
Here the focus is building the immune system, building a body where the cancer can't live. Not necessarily killing the cancer, but making a body so the cancer doesn't want to live there. That's a big difference.

[06:33]
Other places they just want to kill the cancer and kill your immune system. So it's just about trusting that there are results here. Real results, and people are living long, long lives after coming to ITC and receiving the treatments.
