At the A1 level, you only need to know that 'cancro' is the word for 'cancer' in Portugal. You might see it on news headlines or in very basic health warnings. It is a masculine noun: 'o cancro'. You don't need to know technical details, just that it is a serious illness. Example: 'O cancro é uma doença' (Cancer is a disease). At this stage, focus on the pronunciation, which has a nasal 'a'. This is one of those words that sounds very different from its English counterpart despite looking similar, so listen carefully to the 'an' sound. You should also be aware that in Brazil, the word is different ('câncer'), which is helpful if you travel between the two regions.
At the A2 level, you should be able to use 'cancro' in simple sentences about health and lifestyle. You can talk about prevention, such as 'Não fumar ajuda a prevenir o cancro' (Not smoking helps prevent cancer). You should know how to specify common types of cancer using the 'cancro de + [organ]' structure, like 'cancro da pele' (skin cancer). You might also encounter the word when talking about your family history or general news. At this level, you start to see the word as part of common phrases like 'luta contra o cancro' (fight against cancer). You should also recognize it as a zodiac sign in horoscopes, which is a fun way to practice reading.

You will learn related vocabulary like 'cura' (cure), 'tratamento' (treatment), 'quimioterapia' (chemotherapy), and 'radioterapia' (radiotherapy). You can express opinions or feelings about the disease, such as 'É importante apoiar quem tem cancro' (It is important to support those who have cancer). You will also notice the metaphorical use of the word in political or social contexts to describe something very bad that needs to be removed, like corruption or poverty.
At the B2 level, you can engage in detailed conversations about the healthcare system and how it handles 'cancro'. You will understand the nuance between 'cancro' and 'neoplasia' or 'tumor'. You can read articles about scientific research and clinical trials. You should be comfortable using the word in formal writing, following all grammar rules regarding gender and pluralization. You will also understand the cultural sensitivity surrounding the word in Portugal, where it is sometimes avoided in favor of euphemisms in polite company. You can discuss the social impact of the disease, including the work of NGOs like the 'Liga Portuguesa Contra o Cancro'.
At the C1 level, you have a deep understanding of the word 'cancro' and its various registers. You can read complex medical literature or legal documents related to health insurance and cancer coverage. You understand the historical etymology of the word and how it has evolved in the Portuguese language. You can use the word in sophisticated metaphors and understand its use in high-level literature. You are also fully aware of the regional differences and can switch between 'cancro' and 'câncer' depending on your audience without any hesitation. You can debate the ethics of cancer research and the distribution of healthcare resources.
At the C2 level, your mastery of 'cancro' is equivalent to a native speaker.

cancro en 30 secondes

  • Cancro is the European Portuguese word for cancer, a serious medical condition involving abnormal cell growth.
  • It is a masculine noun ('o cancro') and is also used for the zodiac sign Cancer in Portugal.
  • The word is distinct from the Brazilian Portuguese 'câncer', making it a key regional identifier.
  • It can be used metaphorically to describe a destructive force within society, such as corruption.

The word cancro is the standard term used in European Portuguese (Portugal, Angola, Mozambique, Cape Verde, etc.) to describe the medical condition known in English as cancer. It refers to a broad group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. In the linguistic landscape of the Lusophone world, the distinction between cancro and the Brazilian term câncer is one of the most prominent lexical differences between the two main variants of the language. While a person in Lisbon will always say 'cancro', a person in Rio de Janeiro will always say 'câncer'.

Medical Context
In a clinical setting, doctors use the word to classify various types of malignant neoplasms. It is often followed by the specific organ affected, such as 'cancro do pulmão' (lung cancer) or 'cancro da mama' (breast cancer).

A detecção precoce do cancro aumenta significativamente as hipóteses de cura.

Beyond the purely biological definition, cancro is frequently used metaphorically in social and political discourse. It describes something that is perceived as an evil, destructive force that spreads through a system, such as 'o cancro da corrupção' (the cancer of corruption). In this sense, it implies a deep-rooted problem that requires drastic measures to eradicate. It is also the name of the fourth sign of the Zodiac in Portugal, corresponding to the English 'Cancer' (though 'Caranguejo' is also used to refer to the crab symbol itself).

Zodiac Usage
When referring to astrology, the word is capitalized: 'Eu sou do signo de Cancro'. It covers those born between June 21 and July 22.

Muitas instituições em Portugal dedicam-se à investigação do cancro.

Social Register
The word carries significant emotional weight. In casual conversation, people might use euphemisms like 'aquela doença' (that disease) or 'uma doença prolongada' (a prolonged illness) to avoid the harshness of the word 'cancro'.

O meu avô superou um cancro de pele no ano passado.

O tabaco é a principal causa de cancro do pulmão.

In summary, 'cancro' is a versatile and heavy word. It spans from the highly technical vocabulary of oncology to the mystical realm of astrology and the critical realm of social commentary. Understanding its usage requires sensitivity to the context and the regional variant of Portuguese you are speaking.

Using 'cancro' correctly involves understanding its grammatical properties as a masculine noun and its common prepositional pairings. In Portuguese, nouns designating diseases are typically preceded by the definite article 'o' or 'a'. For 'cancro', we use 'o' (o cancro). When specifying the type of cancer, we use the preposition 'de' followed by the definite article corresponding to the organ or body part. For example, 'o cancro do pâncreas' (the cancer of the pancreas) or 'o cancro da próstata' (the cancer of the prostate).

Specifying Types
Use 'de' + [Article] + [Organ]. Example: 'O cancro do cólon' (Colon cancer).

Ela está a fazer quimioterapia para tratar o cancro.

When discussing the 'fight against' or 'treatment for' cancer, certain verbs and prepositions are standard. You 'luta contra o cancro' (fight against cancer) and 'trata o cancro' (treat cancer). If you are referring to someone having cancer, the verb 'ter' (to have) is most common: 'Ele tem cancro'. Note that in this general sense, the article 'o' is often omitted after the verb 'ter', similar to how we say 'ter febre' (to have a fever).

Verbal Collocations
Ter cancro (to have cancer), vencer o cancro (to beat cancer), diagnosticar um cancro (to diagnose a cancer).

O cancro não é uma sentença de morte hoje em dia.

In formal writing, especially in medical journals or news reports, you will see 'cancro' accompanied by adjectives like 'maligno' (malignant) or 'metastizado' (metastatic). It is also common to see the phrase 'doença oncológica' (oncological disease) used as a more formal synonym to avoid repetition of the word 'cancro'.

Adjective Agreement
Since 'cancro' is masculine, adjectives must agree: 'cancro invasivo', 'cancro agressivo'.

A ciência fez grandes progressos na cura do cancro.

O meu signo é Cancro, por isso sou muito emotivo.

By mastering these patterns—article usage, prepositional phrases for body parts, and common verbal collocations—you will be able to discuss this sensitive topic with the appropriate level of accuracy and respect in Portuguese.

You will encounter the word cancro in a variety of real-world settings in Portugal and other non-Brazilian Portuguese-speaking regions. One of the most common places is in the mass media. News broadcasts frequently report on medical breakthroughs, government health initiatives, or public health statistics. You will hear phrases like 'rastreio do cancro' (cancer screening) during national awareness months. For example, 'Outubro Rosa' (Pink October) is a major event in Portugal focused on 'cancro da mama'.

In the Media
News reports: 'O governo anunciou novos fundos para o combate ao cancro'.

Ouvi no telejornal que o cancro da pele está a aumentar.

In a medical or hospital setting, the word is used with clinical precision. You will see it on signage in hospitals (e.g., 'Unidade de Cancro'), on brochures for patients, and in consultations. Portuguese healthcare professionals are generally direct but compassionate, and they will use 'cancro' when discussing a diagnosis, though they may also use the more technical 'neoplasia' or 'tumor maligno'.

At the Hospital
Signage: 'Centro de Investigação de Cancro'. Consultations: 'O resultado da biópsia confirmou o cancro'.

Fiz um donativo para a Liga Portuguesa Contra o cancro.

In everyday life, unfortunately, the word is heard when people discuss the health of friends or family. Because of its severity, it is often spoken with a lowered voice or a somber tone. You might also hear it in academic settings, particularly in biology or medicine classes at universities like the University of Coimbra or the University of Lisbon, where students study the cellular mechanisms of the disease.

Academic/Scientific
Lectures: 'A genética desempenha um papel crucial no desenvolvimento do cancro'.

Na faculdade, estudamos as mutações que levam ao cancro.

O horóscopo diz que hoje é um bom dia para quem é de Cancro.

Whether in a serious news segment, a medical consultation, or a casual conversation about the stars, 'cancro' is a word that appears across the spectrum of Portuguese life, carrying with it the specific linguistic identity of the European variant.

The most frequent mistake English speakers make when learning Portuguese is using the Brazilian term 'câncer' when they are in Portugal, or vice versa. While both words are technically understood across the Lusophone world thanks to the internet and soap operas (telenovelas), using the 'wrong' one will immediately mark you as a foreigner or as someone who has learned the other dialect. In Portugal, 'câncer' sounds Brazilian; in Brazil, 'cancro' sounds archaic or European.

Regional Confusion
Mistake: Using 'câncer' in Lisbon. Correct: 'cancro'.

Não diga 'câncer' em Portugal; diga cancro.

Another common error involves gender. Many English speakers assume that abstract or medical terms might be feminine (ending in -o but being exceptions, or confusing it with 'doença' which is feminine). However, 'cancro' is strictly masculine. You must say 'o cancro', 'um cancro', 'este cancro'. Using the feminine article 'a' is a grammatical error that will confuse listeners.

Gender Error
Mistake: 'A cancro'. Correct: 'O cancro'.

O tratamento para o cancro (masculino) é muito caro.

Pronunciation is another hurdle. English speakers often try to pronounce the 'a' like the 'a' in 'cat' or 'father'. In Portuguese, the 'a' before an 'n' is nasal and closed [ɐ̃]. It sounds more like the 'u' in 'butter' but spoken through the nose. Failing to nasalize the vowel makes the word sound like 'cakro', which is incomprehensible. Furthermore, the 'r' is a tapped 'r' (like the 'tt' in 'better' in some American accents), not the English 'r'.

Pronunciation Pitfall
Mistake: Pronouncing it like 'can-crow'. Correct: 'kuh-n-kroo' (with a nasal 'uh').

A pronúncia correta de cancro requer a nasalização do 'a'.

Devemos ter cuidado ao usar a palavra cancro em contextos sociais.

Finally, learners sometimes confuse 'cancro' (the disease) with 'caranguejo' (the animal). While 'Cancro' is the name of the zodiac sign, if you are at a seafood restaurant, you must order 'caranguejo'. Ordering a 'cancro' would be very confusing and slightly morbid!

In Portuguese, as in English, there are several ways to refer to cancer depending on the level of formality and the specific medical context. Understanding these alternatives will help you navigate different social and professional situations. The most common synonym is neoplasia, which is the technical medical term for any new and abnormal growth of tissue. While 'cancro' specifically implies malignancy, 'neoplasia' can be 'benigna' or 'maligna'.

Cancro vs. Neoplasia
'Cancro' is the common name for malignant disease; 'Neoplasia' is the clinical term used by doctors in reports.

O médico falou de uma neoplasia, mas confirmou que era um cancro.

Another frequently used word is tumor. It is important to note that not all tumors are cancers. A 'tumor' is simply a swelling or a mass. In Portuguese, you will hear 'tumor benigno' (benign tumor) and 'tumor maligno' (malignant tumor). The latter is synonymous with 'cancro'. In casual conversation, people often use 'tumor' as a slightly less frightening alternative to the word 'cancro'.

Cancro vs. Tumor
'Cancro' is always malignant; 'Tumor' can be benign or malignant. 'Tumor' is often used to soften the blow of a diagnosis.

Ele trabalha na ala de oncologia, tratando doentes com cancro.

For the zodiac sign, the alternative is Caranguejo. While 'Cancro' is the official name of the constellation and the sign in the Portuguese astrological tradition, many people refer to the sign by the name of its symbol, the crab. You will see both in horoscopes, but 'Cancro' is more traditional for the sign itself.

Cancro vs. Caranguejo
'Cancro' is the sign; 'Caranguejo' is the crab. Both can be used to describe someone born under the sign.

Ela é Cancro, mas prefere dizer que é Caranguejo.

A pobreza é um flagelo, tal como o cancro é para o corpo.

By knowing these synonyms and nuances, you can choose the word that best fits the context, whether you are reading a medical report, talking to a friend, or checking your daily horoscope.
